Spinning Wheel Picker

prusaprinters

This model is to make a selector wheel to pick randomly from 1-20.  It is designed for ABS but should print well out of any relatively rigid filament (with some scaling adjustments).  The “flapper” was printed out of 85A TPU with 100% infill.  It will need 1 - 608 bearing and 21 - M3x30 bolt head cap screws.  I also used heat set inserts for the screws, specifically, the M3x3 insets from CNC Kitchen.  I used a drop of glue to hold the flapper in as well as the center plug to the bearing.  The 2 color wheel is just a simple filament swap after layer 20 (if printing at 0.2mm layers).
