RapMan 3.x Corner Set

This is a complete set of printable corners for the RapMan 3.x printer from Bits From Bytes.

They may be used as stronger replacements for the (very fragile) standard acrylic corners, and are designed to be installed without having to take the whole machine apart. Most corners now require only 3 easily-accessible bolts (down from 8), and importantly, no more fiddly grub screws :)

Apart from making the whole machine stronger, the Z motor corner now includes a mechanism to easily and accurately adjust the tension on the Z belt. This is now a one-handed operation, not three-handed!

The Y motor corner requires 2 files (top_backleft.stl, ymotor_clip.stl) whilst the Z motor corner requires 4 files (bottom_frontright_backleft.stl, zmotor_*.stl) All other corners are each 1 file only; even the top corners, as the bearing holders are now all integrated.

I have endurance-tested these parts with a 24-hour non-stop print and everything is still running smoothly. If I find any weaknesses, I will update the STLs.

NB: Some of the green STL auto-renders displayed left and below are mirrored; they are however correct once you download them (tested in both BFB Axon and MiniMagics)
