Large computer volume control knob
thingiverse
65mm oversized USB volume knob. Uses all Adafruit gear: rotary encoder, trinket & gemma (temp till rev 2), and 16 pixel NeoPixel ring. Instructions Print all three files: knob,base and cover. If using a NeoPixel ring for illumination, print the knob in a natural/clear filament. For the knob I suggest concentric infill and concentric top and bottom fill patterns. Obtain parts from Adafriut: Trinket: (trinket, trinket pro, gemma, flora etc)https://www.adafruit.com/products/1501 Rotary Encoder:https://www.adafruit.com/product/377 Optional: NeoPixel Ring:https://www.adafruit.com/products/1463 Gemma/Trinket To program and wire I used Adafruit's tutorial:https://learn.adafruit.com/trinket-usb-volume-knob Use a little hot glue to secure the neopixel ring in the recess, trinket to the base cover and the cover to the base.
