Grandpa's Greatest Bike Chain Fidget

I love the simple way these fidgets work. I added a chamfer to the inside edges for a comfortable feel. You can mix and match the colors, textures, and even “hot swap” filaments during printing for even crazier combinations! The possibilities are limitless!

They work great with a .2 layer height, 3 walls, and no infill. 

I put all four texture types in the “collection” stl file, and each one has an individual file if you prefer to print only one style.

I used these 25mm keyrings from Amazon.

Need a quick print to test your first layer?
