Open Hardware Fidget Key Chain

This is a remix of my Open Hardware Fidget, it's modified to be smaller and I added a loop for a key chain.

Description

I made this model as a fun project. I remixed it from my original model that is larger and doesn't have a key chain hole. It's fun to play with, all the teeth can be rotated and so can the inner ring. 

I've made two versions, one with a stronger and larger hole. This isn't true to the original model, but does allow for slightly larger key rings. I don't expect this to be extremely tough, the mechanism is delicate and the key hole relies on the layer binding strength. 

When printing this, you can either use the supplied 3mf files and use the custom painted seams or paint them as shown below. It's important that the seam isn't on the rotating parts, or the parts that move close to each other or it might bind.

 

I printed the models with the new input shaping firmware on the Prusa MINI+ and they came out great! 

The Fusion 360 file is included so the remix can be further remixed.
