cut some volume off of the front or back pieces where they touch sides

there is a printing issue where a fat couple layers jut out a bit on the
edge where the front or back piece would touch a side piece or another
front or back piece, making them not connect that flushly. this removes
a bit in order to let that fat layer be in a gap instead
