Knob replacement for gas stove

thingiverse

A coworker asked me if I could design and print a turn knob for his small gas stove, as the original broke an he could not find where to buy a replacement. I did it, it worked on second print. So I figured might as well give it to the world. Note that the valve shaft is 5 mm in diameter, and has two parallel notches, one on each side, for a lock (potentiometer shafts have a single notch for locking). Anyway, look at the pictures if you don't know what I mean, make sure it's what you got. Try it first. If it's not tight, use crazy glue or epoxy. The STL file is named "...-0.1mm.stl" because I shrunk back all faces by 0.1 mm to at least partially compensate for average printer tolerances (printers make models about 0.2 mm bigger in x and y, by ignoring extrusion radius). Preferably use the provided gcode. It is generated with Simplify 3D, for Creality CR-10S and using PLA; but, a) I placed the knob near the 0,0 corner --NOT in the center of the table-- so that people with smaller printers can still print it. And as for PLA-ness, you can manually override the temperatures and fan speed as the print stars, to suit other materials. Model cooling fan speed is zero for layer 1, then goes to 100% for layer 2 and onwards; so if you need to override it do so at the start of the second layer. Enjoy.
