Symetric skateboard trucks jig

by GrabCAD
high school engineering project I did to create a jig to align holes on a skate board or longboard. I 3d printed a model then put #10-1/2 Brass fittings in the holes to create a tight fit for a drill to drill holes straight down. it also includes a stencil for drop through truck cut outs. and I believe it was a .5" x .125" x 4' flat rod that went through the center. this way it came move up and down for cambered or rockered boards but cannot move left or right.
