Connector soldering helper

I dind't find any so I made this thing to hold connectors at an angle (15 degree steps) for easier soldering.

Works with D sub connectors up to DB-25, DVI, round connectors and probably more.

Materials required:
- 1x 100mm M6 screw, hex head, the one I used only has 20mm of threads at the end
- 1x 40mm M4 screw
- M4/M6 washers and nuts
- a small spring for the angle adjust
- a reasonably soft spring for the jaws (depending on the size(s) of the connectors you want to use), around 80m
