(Customizable) Arcade Spinner Knob / Rotary Encoder Knob

thingiverse

I'm building an Arcade spinner for Arkanoid and Tempest using a knob from a rotary encoder. I've added some weight by attaching M5 nuts and M3 screws to improve spinning. The holes in the top part of the knob need to be tapped so you can connect both halves via M3 screws or glue them together without using screws. If anyone wants, I can share the Arduino code later, which is basically a quick adaptation of rotary encoder example code inserted into the mouse functions of the Arduino library. I'm using an optical encoder with 600 pulses per rotation, available for about 10 euros on Aliexpress: https://www.aliexpress.com/item/1000-Pulses-Incremental-Optical-Rotary-Encoder-AB-Two-phase-5-24V-Incremental-Optical-Rotary-Encoder-600/32894471123.html Use the customizer to adjust the model if your encoder or its shaft differs from mine.
