This project was an idea suggested to me and my students for a fundraiser. Students learn to print the main object(s), then complete the circuitry needed to make it a functional model. As for the shell that goes around this, we simply used posterboard because it was a little quicker to make than 3D printing all of the walls as well. Teachers throughout the school loved this idea.

This project was not solely my idea, just the 3D model. You can find the full video with instructions on how to build it here:

-Remove from print bed
-Grab a xacto knife or spatula to remove the raft from the model
-Grab a pair of thin needle nose pliars and begin removing supports carefully
-For the supports under the "chamber" part of the model, I used the flat end of a pencil to push those off from the opening.

-I did not use acetone on the model to clean it up further, but you could use lightly to polish up areas where supports didn't come off the cleanest.

Took me about 20-30 minutes to make the full model on Fusion 360 while watching the video. It was a little tricky getting all of the dimensions, as some are not given in the video. I guess that's where the artistic side of this project comes in!
