Very cool concept
Screw Sorting Machine
Thanks for the suggestion - I've now added an .stl file. I chose vacuum forming because it's more accessible, and for this project, where you need to mass produce the same part, it's faster and cheaper. It also allows you to scale this up much bigger. Having said that, it is by no means a better approach. 3D printing these shapes would allow for far more complex designs, and by using a low infill, you could help diffuse the harsh light of LEDs, and create really cool light effects because of the internal walls of the print. I would be really interested to see the result!
