Trimmer Bump Knob

Designed this part to replace the most commonly wear part. Fits Ryobi P2009 Trimmer head.

Infill: Sliced in Cura I used a split Infill where the bottom 75% of the model at 20% infill and the top 25% of the model (the part that’s takes the brunt of scuffing on the ground) at 100% infill

Supports: Use supports. I used grids at 15% density

This design does not work with the Easy Wind handle. If there is interest I can modify to work with that also.

Update: Uploaded revised file (aka ReIndexed) to correct for ratchet steps being out of phase by 30 degrees.
