Penny Fidget Spinner

thingiverse

Yet another innovative fidget spinner emerges, inspired by the ingenious suggestions and meticulous process from Joel, also known as the "3D Printing Expert," as showcased here: https://www.youtube.com/watch?v=EgOuvOLiwAM. The snug fit ensures that pennies remain securely in place. However, it required some force to insert them, possibly due to my printer's calibration issues (measured prints showed a size increase of about 0.1-0.5%). You may need to upscale the design by a few percent for effortless assembly. Customizable caps feature monogrammed designs, but I've also uploaded blank versions for those who prefer a clean slate. To create this fidget spinner, simply print, insert a bearing, and add 15 pennies, along with the caps. Enjoy! (Drop me a note if you're interested in obtaining the Fusion360 files.) Update: For a more durable take, I printed one out using Ninjaflex, but it required gluing the pennies in place to ensure they stay secure.
