3 Sided USB drive spinner

thingiverse

This is a USB drive embedded inside a fidget spinner originally designed for my son, who now shares it with my wife. You can find more information about this project on my blog at https://nirrobotics.com/2017/05/the-usb-spinner/ To build this device, you'll need to use a 4x13x5mm 624 bearing and a standard USB drive commonly found in drives purchased from AliExpress. Two 1/4-inch nuts will serve as counterweights. During printing, pause the process just before the layer that covers all internal holes, which are designed to be completed at the same height for easy access. Insert the bearing, dive into the USB drive, and secure it with the two nuts.
