Knob for Nerdy Gurdy

thingiverse

This is a design for a knob that fits a Nerdy Gurdy. The knob consists of two parts that screw together almost perfectly, creating a seamless joint that's barely noticeable to the touch. You can't even feel it with your fingernail. Only one bearing is required, which is inserted into the outer knob and held in place by the inner part once it's screwed in. To print this design, face the sphere side down, which necessitates supports. I recommend printing at a maximum layer height of .15mm to achieve decent resolution on the printed threads. This design was created using my Fscad framework.
