Hypercube Evolytion Z linear rail support

I made this thing specially for use with "mlabruyere"s Z carriage for the Hypercube Evolution; https://www.thingiverse.com/thing:2527941 I like that carriage because the bearings are fixed with screws, but the problem is that it was hitting the axis mount and it's screws.
Surprinsingly that Z carriage is also published by "Foden7" here https://www.thingiverse.com/thing:2570798, I don know which one came first.

They are fixed only on the top and bottom of their respective 3030 profiles, with a more robust build to compensate for the fixing position. I used M3 nuts and a different fixing method for the rod which is easier to get right on old printers (like I am using). You will need M3x16 hex screws.

New v1.2: added 1mm spacing to avoid the Z-Carriage hitting the structure

These were designed wit the excellent online free CAD OnShape and can be found here
