Huge tolerance was because my printer was overextruding in the ancient
past when I designed this (something something bad hobbed bolt making
life hell).
$fn = 64;
-hole_tolerance = 0.6; // widen holes a bit, may still need to drill out
+hole_tolerance = 0.3; // widen holes a bit, may still need to drill out
// Size of mounting bolt heads so they can be recessed
bolthead_depth = 2;
plate_cut_bolt = 3 + hole_tolerance;
plate_cut_x_bolt_offset = plate_cut_distance + plate_cut_bolt / 2;
-plate_extra_height = 4; // make plate a bit taller so it is structurally sound
+plate_extra_height = 6; // make plate a bit taller so it is structurally sound
plate_height = plate_cut_height + plate_cut_y_offset + plate_extra_height;
