Toy Conveyor Belt

Description

A Factorio-inspired toy conveyor belt you can pick up and play with, kind of like a fidget spinner. It has a Transport Belt aesthetic from the Factorio game.

Watch the design video to see how it was made!

Printing

Print the 4 plates in the “plates” file with PLA. The settings should be dialed in for scaling (to offset shrinkage), infill, and supports. The plate names correspond to the color and layer height the plate should be printed with. For e.g. "Light Gray 20" reads "Print with light gray filament w/ 0.20 layer height". 

There are a few sizes of shaft key STL files (ShaftKey385, ShaftKey390, ShaftKey395) you might also want to print in case it's too tricky to press-fit them in.

I used the colors below (outlined in red) from Bambu Labs.

Assembling

Watch the assembly portion of the design video for assembly instructions (assembly starts at 5:27)

If there is too much friction between the shafts and the side rail holes, you can dab a bit of Super Lube (I used 92003), and it should work great.

Let me know if you have any questions or if there are any issues. Happy to make adjustments if needed!
