Update:

I've updated all files with a new version. The newer version is shorter and the drill chuck can reach into the drill guide. With a 2.5mm drill, I can drill 16mm in one step. I suggest to print these with a brim, due to the narrow surface.

This is a dilling guide for offset snaps to mount multi board grids.

This guide is used to pre drill holes for wood screws. It comes in 3 variants for the following wood drills (2mm, 2.5mm, 3mm).
It works with a single, dual and quad offset snap.
