A Tetrix drill guide for drilling holes into raw materials with the spacing and sizing of a Tetrix beam (or at least the one I have).
Earlier this year, I found a Tetrix Drill Guide right here on Thingiverse. I printed it for our team (FTC Team 4480 Blue Dwarves) to use this season. However, I recently learned modeling, so I decided to make a different one with the exact hole sizes and spacing (at least, to the beam I have right now).
I measured the spacing between holes (each large hole is 16mm apart, same for any small holes that are separated by a large hole) and the sizes of the holes themselves (3.5mm for small holes, and 8mm for large holes).
