Replacement knob for kitchen pot lid

It's a replacement knob that takes a threaded heated insert. It's parametric too so you can change the shape a little and more importantly choose the threaded insert size. Obviously you might want to use a heat resistant filament. I use Protopasta HTPLA which I then anneal and it seems to do the job fine; it doesn't warp when cooking and also survives the dishwasher.
