Ball Transfer Roller Fidget / Keychain

This is a fully functional ball transfer roller print-in-place model with an internal roller bearing. All print settings are pre-set in the profile, allowing you to print it as it is. Tested with Bambu Lab PLA/Basic, PLA/Matte and Extrudr PLA Silk How to break it in after printing: 1.Press crosswise from above until you hear a cracking sound. 2. Rotate the ball around the Z-axis to free the ball bearing inside. 3. Smooth out the ball transfer roller with 360° rotations Boost MeHave fun :-)
