This provides holders for common US pegboards with quarter-inch holes spaced 1 inch apart. I'm talking about the non-metallic kind that are roughly 1/8 to ¼ inches thick. I took the peg hooks from another design (https://www.thingiverse.com/thing:4316521) and used Prusa slicer trickery to replace the original hooks. The rest of the parts are from the original.
