This vice will hold electronic boards firmly for soldering. The vice makes a good platform to rest a hand on so the vice is portable and does not need to be fastened to the work bench.

The vice was printed with PLC, the heads and extenders are in black, and the jaws in white. The jaws are attached with 4mm screws so the jaws can be changed. One or two rubber bands are used to provide tension on the jaws. There are knobs to attach rubber bands on both side of the heads. The extenders can be printed as long as desired, these are 95mm so they can be made on a printer with a 4 in cubed print space. The 3D CAD file is included in the files so modification can be made.

Print the 7 pieces in the three stl files, Heads, Jaws, and Extenders. I printed these parts with a brim, and 20% infill. The jaws I printed 100% infill.

The three extenders need to be glued to the two heads The sides of the extenders need to be cleaned of excess plastic, and filed so the two halves slide smoothly. Test fit these parts before gluing. I used hot glue to attach the extenders to the heads.

Attach the jaws to the heads with four 4mm screws and nuts. Slide the two halves together and use one or two rubber bands to provide firm tension on the part in the vice. A small rubber band on one end seems to work well.
