Vernier caliper's jaw adapter for disc brake rotor

I made these adapters to use my Mitutoyo 530-122 vernier caliper to measure wear on my car disc brake rotors and avoid the outer lip left when the rotor sees a lot of wear.

The offset should be 20 mm, if your printer is not accurate enough you can use a file or nail file to adjust the contact point of the pins.

The model is parametric but I think not enough to be universal.
