Kraft RX-044 RX-045 Einhandzwingen Verbinder (customizable Quick Grip Bar Clamp Coupler)

Recently I found this nice coupler for Parkside or Powerfix quick grip bar clamps:

It prints & fits really nice on said clamps, but I don't have a lot of them.

Most of my cheap quick grip clamps are "Kraft" or "Walter" branded clamps sold by NORMA, a competitor of LIDL supermarkets here in Germany.

The "Kraft" clamps are actually built a little sturdier than the Parkside ones, especially the lever mechanism is quite a bit more solid.

So I took some measurements and went to recreate a similar coupler for Kraft RX-044 (150mm) and RX-045 (300mm) clamps in OpenSCAD.

I put some comments in the .scad file, so it should be possible to adapt this coupler to other makes / dimensions of similar quick clamps.

I also added texts on both sides, so different couplers can be marked differently and don't get mixed up.
