Ethan Roby’s Rube Goldberg Machine Portfolio

I made a Rube Goldberg machine that rings a bell using 3D printing, laser cutting, and milling. Some research I did before making this project included looking up images and videos of Rube Goldberg Machines.

I started out by creating the tilters (figure 2) for the first part of the Rube Goldberg machine. I took measurements of the peg board I would be using to put the tilters on and recreated it in Fusion 360. This allowed me to figure out how big I needed my tilters to be, where to place the pivot point, and what the finished product would look like. Then I printed them on a Flashforge Finder. Next I created the ball-run section. I did this by taking measurements of the piece I would be milling it from then recreating it in Fusion 360. I then drew the path for the ball and cut it out of the model I had in Fusion 360 (figure 1) and used the fillet tool to round out the path. Then I cut it on a Carvey. Lastly I laser cut the dominos using Inkscape. I made the canvas size the same size as the piece of wood I would be cutting them from. To create the dominos I used a 2:1 ratio for the size. Increasing the size on the 1 by 0.1 of an inch every domino (figure 4). I then laser cut them on a Rabbit laser cutter.

Figure 4
Software I used for this project were Fusion 360 and Inkscape to design the pieces, and to fabricate them I used a Flashforge Finder, Rabbit laser cutter, and a Carvey. For taking measurements I used digital calipers, a pencil, and a notebook.

The way I used each type of fabrication is:

  • I 3D printed the tilting pieces because it would not be possible to make with the laser cutter and the milling machine would take up too much time and resources.
  • I laser cut the dominoes because I needed the speed of laser cutting and they were thin enough that it did not make sense to mill it.
  • I milled the ball-run section of my Rube Goldberg machine because I needed the 3D capability of Milling but the speed of laser cutting however without wasting a lot of material.

Some challenges I encountered was figuring out the right size for the rings that snap onto the tilting pieces to hold them onto the peg board. I overcame it with trial error over a few versions (figure 3). I eventually figured out the hole needed to be 6.7mm in diameter.

Some things I learned throughout this project were how to utilize the advantages of 3D printing, laser cutting, and milling, and that it takes a lot more time that it seems to design and create a Rube Goldberg machine.

Ethan Roby’s Mancala Board Portfollio

My prompt was to create a Mancala board using a milling machine. I made my Mancala board by taking measurements of one in real life and the piece of wood i would be cutting it from. Then I recreated both of them in Fusion 360. The main tools I used in Fusion 360 are line, circle, rectangle, fillet, and extrude. Extrude turns the 2D sketch into a 3D shape. To cut out the Mancala board I used pocket clearing and two parallel passes perpendicular to each other. I used the parallel passes to help smooth it out. Once I was ready to cut it out I exported it to Easel so the Carvey could understand how to cut it out. Then I carved it out on a Carvey.


I started with measuring the mancala board we had using digital calipers. I used those measurements to recreate the mancala board in Fusion 360. Once I had the mancala board in Fusion 360 I exported it to Easel so the Carvey can use the file. I then cut the mancala board out of a piece of wood using a Carvey.
The main challenge I faced was trying to create the paths for the carvey so it knew how to carve out the mancala board, and making sure the chanels going around the board fit inside the boundaries however they ended up not working out in the end.

Ethan Roby’s Double Scale Mini-figure Portfollio

My prompt was to create a Lego ninifigure twice the scale. I made my double scale minifigure by taking measurements of real minifigure pieces with digital calipers. I used the measurements to recreate the pieces in Fusion 360. The main tools I used in Fusion 360 are line, circle, rectangle, and extrude. Extrude turns the 2D sketch into a 3D shape. Then when I would print a piece I would open the file in FlashPrint and double the scale. This means that the scale if the minifigure pieces in Fusion 360 is the same as real life but would double it in flashprint I finished ahead of schedule so I also made a custom TV head for my minifigure.


I started with measuring the real minifigure with digital calipers. Once I had the measurements I recreated the minifigure in Fusion 360. After I finished I used FlashPrint to double the scale and slice it so the 3D printer can understand the file. I printed it using a Flashforge Finder 3D printer.


The main challenge I faced was getting the pieces to fit together without being to loose or too tight. The hardest pieces to make were the arms. The reason why was trying to get them to fit into the sockets on the torso correctly with the right tolerance. I eventually fixed the issue with constant trial and error of changing the size of the pegs on the arms.

Ethan Roby’s Maze Portfolio

My prompt was to make a hand held ball maze. I began by creating the maze pattern. I designed the walls of the maze at complete random. The smiley face in the middle is also there for no reason. To make the walls of the maze I used the pen tool in Inkscape. I made them at random as I went including the smiley face in the center. I took out the fill color of the walls and left the stroke. Next I converted the strokes to paths. This makes the walls thick. I created three layers of the maze and cut them out on a Rabbit laser cutter. There is the bottom layer which has the handles and the outline for the walls so I know here to place them. The middle layer has the walls which I place onto the outlines and glued on with wood glue. Last is the top player, it is the acrylic cover for the maze which is supposed to be held on by four screws. One in each corner. However we at the time we did not have the screws we needed so I used tape, but i still included the holes for the screws just incase.
The main challenge I faced while creating the maze was making sure the ball would fit through it. To make sure it did I made a circle in Inkscape with the same diameter as the ball and move it through the maze.

Fabslam Project

The problem we all decided on was college campus transportation. To solve this problem we came up with the idea of a foldable skateboard that would fit into a backpack so you could take it inside and not worry about someone stealing it as easily as a normal skateboard which sticks out of your backpack. This was one of the things I am most proud of. The moment when we first tried to put it into a backpack and it actually fit no problem.

Working with this group was alright, however just like any group project there was that one person (I am not going to name any names) who does nothing and just slows productivity in the group. We shared our responsibilities very well however. We had two people designing the skateboard, and we had one person working on the paperwork and website. Once the two people working on designs had come up with a good idea they showed it to the rest of the group then we all voted on weather it should be applied to the final product or not. One big problem we had was the hinge. The two people designing it went though many iterations before the entire group agreed on a design. This took about three to four weeks. I personally think that we worked well together.

I feel like I had a big contribution to the project. I brought the wheels and trucks so we would not have to buy them. I chose what grip-tape to buy, and where the holes for the crews should go. These contributions feel important to me because I feel like a really helped with the creation of the foldable skateboard. However I would like to improve it. Currently the hinge is sloppy and not very strong. I would like to fix that by thickening the pin in the middle of the hinge to make it have less slop and be able to support more weight.

I learned a lot from this course. I learned how to build a Jelly Box 3D printer, how the 3D printer works, and teamwork.
Challenges we had during the build was trying to get the screen to work. After hours of trying to figure it out, and a new arduino. We finally figured out that the power for the screen was not properly plugged in.
Things i am most proud of from this build process is when we were finished wiring it and for the first turned it on. Although I was more proud when we got the screen to work.
Working with my team-mates was a great experience working with this team. We have our inside jokes and can get along. The only problem we faced was the screen not turning on and we worked together to figure it out.
I would like to build another. It was a great and challenging experience.

I made a Rube Goldberg machine that rings a bell using 3D printing, laser cutting, and milling. Some research I did before making this project included looking up images and videos of Rube Goldberg Machines.

I started out by creating the tilters (figure 2) for the first part of the Rube Goldberg machine. I took measurements of the peg board I would be using to put the tilters on and recreated it in Fusion 360. This allowed me to figure out how big I needed my tilters to be, where to place the pivot point, and what the finished product would look like. Then I printed them on a Flashforge Finder. Next I created the ball-run section. I did this by taking measurements of the piece I would be milling it from then recreating it in Fusion 360. I then drew the path for the ball and cut it out of the model I had in Fusion 360 (figure 1) and used the fillet tool to round out the path. Then I cut it on a Carvey. Lastly I laser cut the dominos using Inkscape. I made the canvas size the same size as the piece of wood I would be cutting them from. To create the dominos I used a 2:1 ratio for the size. Increasing the size on the 1 by 0.1 of an inch every domino (figure 4). I then laser cut them on a Rabbit laser cutter.

Software I used for this project were Fusion 360 and Inkscape to design the pieces, and to fabricate them I used a Flashforge Finder, Rabbit laser cutter, and a Carvey. For taking measurements I used digital calipers, a pencil, and a notebook.

The way I used each type of fabrication is:

Some challenges I encountered was figuring out the right size for the rings that snap onto the tilting pieces to hold them onto the peg board. I overcame it with trial error over a few versions (figure 3). I eventually figured out the hole needed to be 6.7mm in diameter.

Some things I learned throughout this project were how to utilize the advantages of 3D printing, laser cutting, and milling, and that it takes a lot more time that it seems to design and create a Rube Goldberg machine.

My prompt was to create a Mancala board using a milling machine. I made my Mancala board by taking measurements of one in real life and the piece of wood i would be cutting it from. Then I recreated both of them in Fusion 360. The main tools I used in Fusion 360 are line, circle, rectangle, fillet, and extrude. Extrude turns the 2D sketch into a 3D shape. To cut out the Mancala board I used pocket clearing and two parallel passes perpendicular to each other. I used the parallel passes to help smooth it out. Once I was ready to cut it out I exported it to Easel so the Carvey could understand how to cut it out. Then I carved it out on a Carvey.


I started with measuring the mancala board we had using digital calipers. I used those measurements to recreate the mancala board in Fusion 360. Once I had the mancala board in Fusion 360 I exported it to Easel so the Carvey can use the file. I then cut the mancala board out of a piece of wood using a Carvey.
The main challenge I faced was trying to create the paths for the carvey so it knew how to carve out the mancala board, and making sure the chanels going around the board fit inside the boundaries however they ended up not working out in the end.

My prompt was to create a Lego ninifigure twice the scale. I made my double scale minifigure by taking measurements of real minifigure pieces with digital calipers. I used the measurements to recreate the pieces in Fusion 360. The main tools I used in Fusion 360 are line, circle, rectangle, and extrude. Extrude turns the 2D sketch into a 3D shape. Then when I would print a piece I would open the file in FlashPrint and double the scale. This means that the scale if the minifigure pieces in Fusion 360 is the same as real life but would double it in flashprint I finished ahead of schedule so I also made a custom TV head for my minifigure.


I started with measuring the real minifigure with digital calipers. Once I had the measurements I recreated the minifigure in Fusion 360. After I finished I used FlashPrint to double the scale and slice it so the 3D printer can understand the file. I printed it using a Flashforge Finder 3D printer.


The main challenge I faced was getting the pieces to fit together without being to loose or too tight. The hardest pieces to make were the arms. The reason why was trying to get them to fit into the sockets on the torso correctly with the right tolerance. I eventually fixed the issue with constant trial and error of changing the size of the pegs on the arms.

My prompt was to make a hand held ball maze. I began by creating the maze pattern. I designed the walls of the maze at complete random. The smiley face in the middle is also there for no reason. To make the walls of the maze I used the pen tool in Inkscape. I made them at random as I went including the smiley face in the center. I took out the fill color of the walls and left the stroke. Next I converted the strokes to paths. This makes the walls thick. I created three layers of the maze and cut them out on a Rabbit laser cutter. There is the bottom layer which has the handles and the outline for the walls so I know here to place them. The middle layer has the walls which I place onto the outlines and glued on with wood glue. Last is the top player, it is the acrylic cover for the maze which is supposed to be held on by four screws. One in each corner. However we at the time we did not have the screws we needed so I used tape, but i still included the holes for the screws just incase.
The main challenge I faced while creating the maze was making sure the ball would fit through it. To make sure it did I made a circle in Inkscape with the same diameter as the ball and move it through the maze.

The problem we all decided on was college campus transportation. To solve this problem we came up with the idea of a foldable skateboard that would fit into a backpack so you could take it inside and not worry about someone stealing it as easily as a normal skateboard which sticks out of your backpack. This was one of the things I am most proud of. The moment when we first tried to put it into a backpack and it actually fit no problem.

Working with this group was alright, however just like any group project there was that one person (I am not going to name any names) who does nothing and just slows productivity in the group. We shared our responsibilities very well however. We had two people designing the skateboard, and we had one person working on the paperwork and website. Once the two people working on designs had come up with a good idea they showed it to the rest of the group then we all voted on weather it should be applied to the final product or not. One big problem we had was the hinge. The two people designing it went though many iterations before the entire group agreed on a design. This took about three to four weeks. I personally think that we worked well together.

I feel like I had a big contribution to the project. I brought the wheels and trucks so we would not have to buy them. I chose what grip-tape to buy, and where the holes for the crews should go. These contributions feel important to me because I feel like a really helped with the creation of the foldable skateboard. However I would like to improve it. Currently the hinge is sloppy and not very strong. I would like to fix that by thickening the pin in the middle of the hinge to make it have less slop and be able to support more weight.

I learned a lot from this course. I learned how to build a Jelly Box 3D printer, how the 3D printer works, and teamwork.
Challenges we had during the build was trying to get the screen to work. After hours of trying to figure it out, and a new arduino. We finally figured out that the power for the screen was not properly plugged in.
Things i am most proud of from this build process is when we were finished wiring it and for the first turned it on. Although I was more proud when we got the screen to work.
Working with my team-mates was a great experience working with this team. We have our inside jokes and can get along. The only problem we faced was the screen not turning on and we worked together to figure it out.
I would like to build another. It was a great and challenging experience.
