Appliance Knob

thingiverse

This is a simple knob designed for everyday appliances; it features a 1/4" round shaft opening. Some devices may require a shaft coupler, which has a 1/4" D opening and can be glued to the main knob as necessary. The original replacement knob costs a hefty $27 each from the manufacturer! To use this part, simply print it on your 3-D printer, and if needed, also print the shaft coupler. Glue the two parts together with proper alignment, and you can even scale them during printing to accommodate slight differences in shaft sizes.
