The models I have found seem to be more or less copies of steel sheet designs, not really adapted for 3D printing. My use case is in test jigs for circuit board in a “bed of nails” (pogo pins) board tester. I need a clamp that:Fully opens vertically, so that the arm gets out of the way for unloading and loading the boardCan hold the board securely against the spring force from multiple pogo pinsFor a toggle clamp to work, the dimensions need to be quite accurate so that the clamp locks in place when the height of the vertical rod is correctly adjusted.
