About this model

Edit 03/17/20: Added a D-shaft version that I'm not able to test but should work regardless. Simple knob for an EC11 style rotary encoder. Made for the serrated shaft not the flat-sided one. Decently snug push fit that may need very slight scaling depending on your setup. This is not meant to fit next to other keys or encoders on a standard 19.05mm grid, it's meant to be used either on a lone encoder or one sufficiently separated from other components. Picture samples were printed at .3mm layer height, 3 floors/roofs, 2 walls, 10% infill. Requires no supports and is oriented for printing already.
