Optical Spinner
Description
This Is A Fidget Spinner Of Course.... The Center Uses 2 Standard 608Z Skateboard Bearings Or Similar (22 Mm X 7 Mm) Stacked Back To Back. Used An Old Pencil Drawing As Inspiration That Typically Keeps Me Occupied When I Sit And Doodle; And Has For Many Years. Most Likely Picked The Shape Up From A Old Math Class Eons Ago. Hope You Enjoy, Hard Let Me Know If I Screwed It Up Anywhere My Eyes Hurt After Staring At It For A While! Version 1 Has More Faces Than Version 2; Also Version One The Bearings Sit Outside The Frame Intentionally. Version 4- Added Some Extra Bearings For Weight And Longer Spinning - Same Size As The Others 7Mm X 22Mm. If You Print It Standing Up It Yields Good Results With A Raft And Supports. Might Have To Clean Inside The Bearing Housing A Bit Or Scale It Up To 101% Depending On Your Printer. It'S A Bit Delicate When Its Done So Use Caution When Installing Bearings.
