Knurled Fidget Bolt Keychain
This design prints in 3 separate pieces: The bolt, the cap, and the spinner. I included 2 versions of the bolt, a shorter version and a longer version. The cap and spinner work for either.
-The bolt is hollowed to allow the storage of "hand-rolled cigarettes" or a little bit of cash. -The cap is reverse-threaded to avoid losing it from the action of the spinner, and to make getting into the "hidden" storage a little less obvious. -Mix and match colors to make your perfect fidget bolt.

Here are the 3d printing settings I used: No Supports Nozzle Size: I have tested these with 0.4 and 0.6 size nozzles and they print great. I don't know about anything bigger. Layer height: The lower the layer height the smoother it will be, but I print them at 0.20 and they work great. Scaling: I haven't tried printing it at different scales, but I wouldn't scale down too much or the clearances may have issues. Scaling up should be ok.
