Geeetech i3 ZX Decoupler

I loved the simplicity of the original design, but it was flawed, probably due to the excessive wobbling of my Z rod: smoothing of the raiser piece along with the positioning of the bolts caused an even worse artefact on the Z axis, layer height inconsistency.

So I went back to Fusion360 and redesigned the thing moving the nuts 45 degrees around and with no fillets.

The result is quite good in my case especially if you look at how much my Z rod was wobbling.
