Parameterized Wheel Spacer

I made this to figure out the right size spacer to order for my 240Z's front wheels to clear the 4 piston caliper swap. It's parameterized, and the parameters are documented in the .scad file. Because I also used this object to machine the hub spacer I ordered, it has a "jig" parameter that will set up the object to hold a spacer with a pilot hole in the center. Both spacer and jig are included as example STL files.

Don't be a dummy and use this in place of a proper aluminum spacer, you will crash and die, and I will have no sympathy.
