Robust and reliable XY Idlers Mount for Hypercube Evolution

I got tired of having my idlers mounts always cracking after some use (and abuse). Even the beefer remixes failed with some time due to cracks developing between layers.

As an engineer I am aware that the position that the mounts were printed rendered a fatigue sensitive part! The tension works against the layers and even the beefer remixes had issues crack propagation due to layers. There are remixes that can be printed standing up but they need an awful amount of supports at areas that I was not comfortable with as they needed mechanical precision to be good.

So I designed these idler mounts to be printed at a position that will not align the layers with loads. They can be printed without any supports. They can use inserts or nuts (form any side). Also these mounts are symmetrical and can be used on both sides. They need 3x M30x30 and nuts each.

"Robust and reliable" is yet to be proven :D

They are **NOT** compatible with 3030R extrusions without interfering with the clos
