EC11 Rotary Encoder Knob

thingiverse

Edit 03/17/20: Added a D-shaft version that should work regardless. Simple knob designed specifically for EC11 style rotary encoders with serrated shafts. The design provides a snug push fit, although some minor scaling may be necessary depending on your setup. This knob is not intended to fit alongside other keys or encoders on a standard 19.05mm grid; instead, it's best used as a standalone encoder or one that's sufficiently separated from other components. Printed samples were created at a .3mm layer height with three floors/roofs, two walls, and 10% infill. The design requires no supports and is already oriented for printing.
