In my latest video, I show how to create custom pegboard holders for my metric and English allen packs. While I’d guess you won’t have the exact same tools in your workshop, hopefully the process will be helpful.
Basically I scanned in the packs with a flatbed desktop scanner, then traced/scaled it to fit in Fusion 360 and extruded. It worked out better than I was expecting, though there was definitely some iteration involved.
Also, don’t make a mirrored image, a mistake which illustrate while creating the second holder. STLs are available here if you just so happen to have the same packs.
