Choose the number of spacers (20 cm each) to fit the thickness of your table and select the proper length screws.

If the parts are printed in the suggested orientations, the vise becomes a really sturdy piece of plastic.

The screw threads are non standard, and optimized for being printed in FDM.

The modular base can be used to develop other applications over it.

I've printed it in ABS (shrinks a bit) and the tolerances ar fine. If you paln to print it in other less shrinking plastics, as PETG, and find the tolerances are too tight, let me know, and I'll provide a looser version.
