My shop has pegboard walls (USA pattern). I wanted to mount my various tool heads for my Dillon 550 bullet reloading press so they would be handy when changing calibers. I found a really nice mount on Thingiverse but it was made to screw directly into a wall. I added a peg pattern to the back in Tinkercad to fit USA standard pegboard and printed it in PLA. The PLA is working just fine but if you are concerned you may want to print in PETG. Here is the link to the Thingiverse original and my thanks to joe9216.
