Fidget Keychain Spinner V1

Made this fidget keychain spinner around 4.5mm BB balls. Originally started as a bearing, but added the extension for attaching keys to it, quite entertaining. - Made for 4.5mm balls (about 14 is perfect). You can resize the model for other sizes i guess?- Insert the balls at the small notch on the body (the last few might snap in). - Would recommend setting Z-seam to random for a smoother bearing race.- Don't really need the cover, only to keep dirt out. - Don't add lubrication!
