Curvier Zippier Fidget Spinner
thingiverse
I fell head over heels for LoboCNC's Zippier Fidget Spinner but was missing the right nuts to use as weights, so I grabbed his hub and married it with the arms from my Curvy Fidget Spinner to create this behemoth. https://www.thingiverse.com/thing:2387340 https://www.thingiverse.com/thing:2790318 Four 608 bearings are necessary for assembly. Use a nice one for the center. Tap gently with a mallet to mount the center bearing! Whacking it too hard may break the gear on top. Printing the zipper in a tough, semi-flexible material like nylon is advised. UPDATE 2018.11.19: I delivered as promised and updated the model to address two issues: the hole for the center bearing was too tight, and the gear on top too weak. The new models (spinner v6 and hub v1) use the same dimensions and friction-fit mechanism for the center bearing, and the gear mounting is reinforced. Also attaching Fusion 360 files for the spinner and new hub. The other STLs are direct from LoboCNC's spinner.
