Ball Bearing Fidget Spinner

myminifactory

Update: I've uploaded a second model that uses half-inch (12.7mm) ball bearings instead of five-eighths (15.875mm) ones if you prefer lighter weight or can't find the five-eighths ones. This new model employs three five-eighths ball bearings as weights, which is standard for everyone else in the world. Originally, these were superglued in place, but I redesigned it to be a bit thicker, and now the balls simply snap into position and hold securely. If you've already made one of these models, please post a photo! Your feedback is greatly appreciated! You might encounter issues with warping, so just add a three-millimeter brim around it, and it should turn out fine. Print this model in PLA at 200 degrees Celsius. To print flat, rotate the model 90 degrees on the X-axis. Materials/Instructions: To get started, you'll need: One "Skate" 608 bearing Three five-eighths (15.875mm) Ball bearings, available in a ten-pack for approximately $4 on Amazon, or Three half-inch (12.7mm) Ball bearings The skate bearing and ball bearings simply press into place. You might need to sand or file down the inside of your printer for the skate bearing to fit properly.
