Longboard light mounts

UPDATE: After 80-100 miles of use it appears that road cracks, speed bumps, cobbles and the ridiculous amount of knobled paving placed at pedestrian crossings has taken it's toll. Both my front and rear lights suffered stress fractures and broke off. To fix this issue I've released the V3 files which have increased the overall thickness of the spacer to 2.5mm and I've added fillets to the light mount bore joint to prevent stress fractures from forming. Hopefully this will fix the problem. Please
