Drill Guide

Parameterised drill bit guide. For corners or mid panel use.

Parameter list:
drill support, this is the depth of the guide, ie default of 20mm gives 20mm guide for drill bit. Higher values better drillbit guidance with higher material usage. 20 is a good compromise.

drill offset, default is 38.1mm for drilling a distance of  38.1mm/2 from the edge, leading to a 38.1mm dowel sitting flush with the edge.
set this to be the thickness of material you are wanting to join and have sitting flush with the edge. the centre of the drill guide is half this value.

guide height, default 20mm gives a 20mm overhang of the guide. if material is thinner than 20mm adjusting this allows the jig to be used on a work top.

guide wall, default 10mm is the wall thickness of the guide.

drill size, default 8mm, Drillbit guide is drill size + drill tolerance.

drill tolerance, default 0.15mm, this oversizes the drill hole guide and allows for the tolerance of the pla.

corner, default false, add a second guide at 9degrees to the first allowing for accurate placement on corners of material.
