Aluminum Longboards

I'm working on some longboard designs, optimized to be cut from stock aluminum on a water jet. This is the first try. The trucks (Randal 180) and wheels (Abec 86mm) were imported from grabcad so I could get a better idea of ground clearance. The idea for this board pattern was taken from Cindrich - check out all their pretty designs!
