This is a fully printable, self centering, table mountable, vise. As you rotate the screw, the 2 jaws move at the same rate. The lead screw can be rotated from either side with a 5mm Allen wrench (5mm hex).

The screw and jaws should be printed out of PETG for strength and the lead screw is 100% infill. There are supports for the lead screw to make sure it doesn't tip during printing. Don't forget to use glue for extra bed adhesion! The base of the vise needs support for the guide plates, I recommend using the PLA interface material so it can be as precise as possible.

Assembly requires the following hardware:

1. 3mm Flat Head Screw x 8mm long - Quantity of 10
2. 3mm Flat Head Screw x 12mm long - Quantity of 4
3. 4mm Cup Point Set Screw x 4mm long - Quantity of 1

There is a left hand thread and a right hand thread on the lead screw, thread the corresponding jaw on to the correct thread and make sure each jaw is the same distance from center before you do the rest of the assembly. The thread will be a little tight so that there is minimal play in the assembly. Lube can be used but make sure you choose a lubricant that is safe for the plastic you decide to use.

When screwing the machine screws into the plastic, do not use too much torque! It is a plastic thread! Same goes for the lead screw, don't use too much toque or it will break!

Spacing of the holes for mounting is 75mm from slot center to slot center. This was designed for use on a X-Carve CNC Router by Inventables to mount to their waste board.

I will add some assembly drawings soon so this all is very clear.
