Coin vise V1

This is a coin vise to help you while you're mechanically cleaning your finds, requires 3x M6 bolts longer than 70mm and 3x M6 wing nuts, the three guiding holes for the vice are 6.8mm wide.

Update: I've uploaded a v2 of the vise which takes a lot less printing material, fits smaller printers (I used a small SLA printer)...the design is much better than this one :) use it instead
