Automatic quick woodworking F clamp replacement jaw for 18x5 rail

A replacement jaw for automatic F clamp. 18×5mm rail, M6 hardware.

I have printed V1 (on the image) but later I've increased tolerances and removed the elongated section (that supposed to be on the other side), but I didn't print the V2. I printed the V1 with ASA, so some warping occured and I had to file the rail guides and the boot didn't come on easily. Inside there are 2 5mm blind holes that might increase strength, I don't have access to FEA.

I printed mine with 0.28mm layer height, 10 walls and 50% gyroid infill with ASA. Heatset M6 nut with soldering iron.
