Jewelry Vice

I could not find a jewelry vice to 3d print so I created one. I have not yet printed it, but I will upload pictures when it is done. It is made to use 3mm and 5mm pins to hold the ring/bracelet in place, however the base is not connected. It uses the weight of the holder to keep it in place so it is not made for high torque or shock situations. So an air graver should be fine but I suggest not going hammer and chisel on it.
