I needed new gas stove knobs that didn't cost me $40 each. 3D printing is an obvious solution!
I needed to modify the thingiverse one ever so slightly to make it fit the gas valves on my range. The SCAD file is what I used to modify the original STL, which isn't uploaded in this. Gotta go get it from the original link.
Printed mine in ABS, so that any heat from the range wouldn't cause any problems. I did use support , printed it in the orientation with the center shaft facing down, like it goes on the stove. Supports came off easy enough and it works great!
The author remixed this model.
