18mm / 3/4" Material Drill Guide (6mm hole) + steel insert
thingiverse
This is a drill guide, helping to drill accurate and true 6mm holes, centred on the edge of 18mm or 3/4" material. There is a larger clearance hole where a steel insert should be epoxied in. This makes the guide last longer as a drill bit will eventually melt away the plastic. The correct mild steel tubing size (which can be cut to size with a hacksaw) for this print would be 10mm OD 2mm Wall 6mm ID https://www.ebay.co.uk/itm/Mild-Steel-Precision-Round-Tube-Pipe-Many-sizes-lengths-Metal-Bar-Rod-Strip-1/253136715957?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 The side that abuts the material to be drilled has channels to allow drilled material to escape. Feel free to remix for different drill bit sizes or material thicknesses.
