This is for drilling axles at a 3 degree angle using a drill press (or a handheld drill with a 2-axis bubble level). It is not meant to locate the holes, just hold the unmodified BSA block for the car at an angle.

Why 3 degrees? I used this on our derby cars to get as much camber as reasonably possible without the wheel crossing the plane of the chassis or exceed our regional rules for overall width. Otherwise, there was no specific science and it prevents from having to bend axles to obtain camber.

I hogged out the walls to save filament. Print without supports.

Enjoy and have fun.
