Z wobble compliant mechanism for SFU1204 ball screw

* STILL IN BETA *This is an anti-wobble system do reduce or eliminate z wobble or z banding using a compliant mechanism at its center. This mechanism has been tried in two version. One with machined part with an insert at the middle and an other version fully printed. Because of the intricate geometries the recommended printing method in SLS. It has been tested in PA12 with good result at 0.3mm ‘’fins'' inside the mechanism.Unlike Oldham coupling it doesn't have any moving part so no backlash.Unlike Wobble X you don't need to redesign anything for it because it's only a spacer. On top of that this mechanism supports forces in both Z directions ( without coming apart or relied on gravity to do his job )The installation is a bit tricky to do because you need to screw down each screws a bit a time so everything can go down all together
