Great thanks to Martin Schneider for his nice design.

Nevertheless I found something to improve ;-) and therefore did a complete redesign.

Although the interface dimensions are identical the parts will be not compatible.

So what did I modify:
- More stiff connection between the side parts, on the top with an M4 screw, on the bottom with the special designed label plate that acts simutaneously as clamp and pulls both side parts together.
- Square shaft for the lower roller made of two halfs, each with a slight step on one side which fits into a pocket on the lower roller and the handle arm. The square shaft half parts are sitting quite strong by purpose. Be aware to fit the slightly elevated ends, one in the foreseen pocket of one lower roller, the other on the opposite side on the handle arm! Fixation is done by M4 countersink screws on either side.
- I didn't like the original straight handle.
