These two plastic vice jaws (125mm, flat and with notches) are used to protect your material during clamping.

The difference to other designs - the magnets sit in slots at the top, are fully protected, and can be fixed such that a removal without damage is possible.

The design is made for 2-3 magnets with a maximum size of 10x2mm (8x2 mm possible).

To fix the magnets, place them in the slot and close with the small printed caps. A drop of glue (blue UHU) fixes the caps. Alternatively you can close the slot with glue.

I printed vice jaws with notches with a powder coated PEI sheet and the others with a regular PEI sheet to get a very flat surface without texture.

I used only 2 magnets but you can also use three for better holding force.

Scale the vice jaws for a larger width.
