This causes an issue with the extruder body, which uses M3 bolts. The nuts at the top of the extruder body are impossible to fit into the nut traps without considerable reworking of the nut traps.

The value given in metric.scad is 5.3mm.

By my measure, it should be 6.28mm.

The following website lists 5.5mm as the "max" allowed for that part of the nut: http://www.roymech.co.uk/Useful_Tables/Screws/Hex_Screws.htm
