Nuke Fidget Spinner

One of my photos showcases the design evolution I began with Tinkercad. I started by creating a simple circle and adding grooves for a lock-washer to fit snugly. However, this initial design needed more weight to function properly. I then modified it to use 5/16" (12.5mm) nuts, which gave me better results but still wasn't perfect. To achieve the desired outcome, I switched to Fusion 360 and landed on a final design that resembles the 'Nuclear warning symbol' by happy accident. This led to the creation of my "Nuke Fidget Spinner". The hole in the center is specifically designed for an 608 (8x22x7mm) bearing. On June 2, 2017, I uploaded a new version of the 608 Bearing caps, which I had redesigned due to issues with breakage when inserting them fully. The new design works much better. On June 14, 2017, I added a new file for the 608 caps called 'Nuke Spinner Caps 8.20'. These larger caps fit tighter and provide improved performance. I also changed the Bearing caps slightly again on June 4, 2017, to enhance their strength and corrected the loading orientation. Additionally, I created a full plate version that includes all the caps and body. For those who may not be aware, removing the bearing shields and soaking the bearings in a degreaser can significantly improve performance. I use TSP, available in the paint section, for 15-20 minutes before drying and blowing out the bearings. This process increased my spinning time from 12-15 seconds to close to one minute without using any lubrication. I also removed the bearing retaining clip on June 4, 2017. The plastic clips that held and centered the balls in the bearing were easy to remove, resulting in an impressive two-minute spin time.
