Rotary vice for electrical installation

Rotary vice for electrical installation.
When installing breadboards, it is necessary to fix them in a position convenient for work. I used a vise from this great design for a while: https://www.thingiverse.com/thing:4300167

But I really missed the following:
- they rotated the breadboard only in two planes, but I wanted it to rotate in three.
- you cannot work (without scaling the vice) with large boards - I use a size of 80 mm

I had to make a modification which so far suits me completely.

Because Since these vices do not experience any load, they can be printed with any settings. All parts are printed without supports in the published orientation. If you have poor adhesion to the table, then it is better to print the kingbolt.stl part with a border
