Smith Corona PWP365DS Typewriter Knob

thingiverse

This is a replacement knob I designed since the original broke off. It's thick and strong at 20% infill and should fit tightly on the shaft. If it's too tight, either take the easy way out and drill it out a bit, or message me and I'll try to fix it for you. It worked fine for my purposes. I'll probably make a replacement back cover as well, so check out my other objects if you need that too. You might need to lay it flat (don't print it in the sideways orientation).
