Universal(ish) Appliance Knob

thingiverse

Replacement knobs for household appliances are easily made by simply measuring the diameter of your broken knob's shaft and resizing the hole on the back of the new knob. Since most appliance manufacturers use standard shaft sizes, this replacement method will likely work across all brands, but it is always a good idea to double-check the size before making any final adjustments. This DIY solution was specifically designed for replacing a faulty dryer knob.
