PCB Wire Bend Caliper

So there's this fancy tool for bending component leads that go into circuit board though holes I found out about last week. I wanted to get one but they are kinda pricey so I just borrowed the one for a bit and reverse engineered it. The actual one has a ruler with marks on it but I'm lazy and don't that it's really all that important. Let me know if you have any issues with the design.

Update: I figured out the threading issue from the original uploaded files. There are two caliper runners now. One for the printed screw and another threaded for an M6 machine screw.
