Floral extruder dial, 5mm shaft

thingiverse

This is a floral extruder design, with a number of deliberate design features. 1) One of the petals has a central cutaway. This allows the user to quickly ascertain the precise orientation of the motor shaft, which can be useful when diagnosing issues. 2) Long(ish) stem allows view of filament running through the extruder gear. 3) Struts between the petals make it easy to turn this manually should you need to. The tolerances are tight on this model (0.2mm clearance). You may wish to enlarge it by a small percentage depending on your printer. Having done a little research this seems to fit a lot of standard extruders, but certainly won't fit them all. I made this using solidworks, so could adapt the model if people have any requests. Printed on Ender 3 Pro 0.2 mm layer height 5% infill (not sure there is any infill at 100% scale) No support No raft or brim Designed to be printed with the larger end against the bed.
