Arc Pinches for Climbing Wall

Disclaimer: Use at your own risk. There is no certainty of print quality. I have had no issues with strength or delamination, but your holds may break on you.

The print profile has TPU for AMS. The texture benefits greatly from sanding for matte texture. The models should have no issues with PLA or PETG.

The included .SCAD file allows you to customize the pinch. The parameters are straight forward but it won't render if you make the angles impossible or increase rounding beyond the size of the hold.

If you generate your own model, you can add fuzzy skin to only the edge like in my .3mf by clicking the model on the plate and selecting ‘fuzzy skin painting’. You can use the fill option set to a low angle to automatically paint only the pocket area. For these models I had to set it in the range of 0.5 to 1 to prevent the fill from applying beyond the edge.
