“Remix of adamghamel's Steam Valve Knob (https://www.thingiverse.com/thing:2251671).” Now remixed again to include a standoff!
The standoff is just tall enough to allow better access to the reset button and stay out of the way for the bed if moved all the way forward. If your printer calibration is honed, a little bit of glue may be needed to keep the standoff and knob together as I allowed for a little bit of flex in printer settings.
The model is best printed upside down using supports.
(Updated photo to include alternative painted rustic/grunge valve)
