Inspired by a video by clough42, I made a metric tap guide for M3.5-M12 taps.

Each tap hole was sized based on Little Machine Shop's clearance data plus a 0.2mm adjustment, plus or minus a fraction of a millimetre based on my printer's tolerances.

The smaller holes seemed to need more adjustment as they were tool small, but from M8 upwards they actually seemed too large! I've only test printed using PLA, so potentially with ABS shrinkage you may need further modification.
