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 80mm
• an alligator clip for the coolant pipe arm, with some heatshrink on the teeth
• G1/8" coolant pipe, the base has a conical hole where the used one I had fits nicely

Placing the main spring on the other side of the jaws so that the bolt sticks out seems to improve functionality even if it looks worse

0.2 (0.3 for the base)

30%

I printed the base with 10% infill and 30% for the areas with the two holders.
I've used supports for the base and vice body, while the jaw can just be printed flat.

Supports removed pretty easily with a boxcutter and a flat screwdriver.
