This is a remix of the Mini Screwless Vice from Naomi Wu (aka SexyCyborg). I enlarged it a little and remodeled it in Inventor, adding a few extra plates and mounting holes. The original is one of the most useful tools I've found on Thingiverse but I wanted a couple of more options, and this is the result. By using the wedges and different combinations of the shims and plates you can clamp small pieces really tightly. The parallels are obviously not of engineering standard, but they're useful if you want to hold a small block level.

For the complete device you'll need: 1 Base 2 Wedges 1 2mm Shim 1 3mm Shim 1 6mm Shim 2 Parallels 2 PCB Clamps 2 Square Clamps 2 Angle Clamps 1 Round Clamp 1 Mirrored Round Clamp

For mounting, you'll need 2 M3 socket head screws at least 30mm long (depending on where you are mounting it).

I have included the Inventor files for anyone who want's to modify them, or just see how it was constructed.

If anyone has ideas for clamping plates, just post them in the comments, and if possible I'll add them to the project.
