Brake caliper bracket fixture

Here's a design for a 3d-printed fixture to machine the angled feature on the brake caliper brackets:

It is mirrored because we need one for each side.

The bracket sits in a pocket and will be held down with its 2 M8 mounting holes, plus a strap clamp using the M6 hole. The mounting holes in the fixture have hexagonal pockets underneath for inserting hex nuts.

The fixture will be bolted down using the counterbored M6 holes, which lie on a 32mm grid to suit my table.

The required cut is aligned with the Y axis.

For reference: at the 8.5 degree angle, a distance of 1mm across the XY plane corresponds to a Z distance of tan(8.5 deg.) = 0.15 mm.
