compact drilling guide, 2-8mm

UPDATED with 2mm hole.

90-degree drilling guide for 2, 3, 4, 5, 6, 7, 8mm drills. Compact design 25mm H, 32mm W, 77mm L. It has two side notches to help with center alignment.

There are three files for different printing tolerances: +0.1mm, +0.2mm and +0.3mm of the drill size. You can use +0.1 and drill a hole in the guide to the exact size or you can use +0.3 and the drill will be very slightly loose. It depends on your printer's precision. I suggest printing 3 walls, so that you can expand a hole in the guide to the final exact size.

Remove the circular pads around notches after printing (these are to help with the adhesion of sharp corners).
