Printing out drilling templates on paper, aligning them, and taping them down to center punch the hole placement kinda sucks. I’ve been working on a 3D printed jig that goes over the enclosure and self centers securely. This is a modified version of the paper template made by General Guitar Gadgets. You can then center punch these areas of your choosing:
- 3×3 grid for potentiometers
- 3 LED placement options
- 1/4 jack on both sides
- DC jack option on both sides
This item is available on Thingiverse for those of you with access to a 3D printer.
