Hermes Baby Platen Knob

thingiverse

This is an exact replica of a Hermes Baby typewriter platen knob, right down to the number of ridges around the edge. Two versions to match the two styles of knob found on this model of typewriter: One with the hole all the way through, and one with the hole capped off. Either one will fit right around the metal anchor piece that screws onto the platen rod. If you use supports (not a necessity depending on your printer's bridging ability) I recommend printing it upside-down so the upper surface comes out nice and smooth. 100% infill. Knob is 25mm diameter x 8mm thick; the hole is 10mm in diameter. If you don't have the metal piece for the center, I also created a modified version that takes the metal collar from a standard 1/4" guitar knob. This way if you're missing the original metal insert - which is impossible to find - you aren't completely screwed. The modified knob is here: http://www.thingiverse.com/thing:2133958
