Triangular bed mount for hypercube

heavily remixed hypercube and custom parts, purpose is to create a triangular bed as my bed mounts on 3 points for levelling, and to maximise rigidity.

my printer is using the original LM8UU bearings for the z carriage.

the normal carriage wasnt sturdy enough for a larger format 3d printer I have, i tried going down the path of dual z-axis steppers which has a set of other challenges, and preferred not to use automated bed levelling which can create artefacts in prints.

all in all, this solved my bed levelling repeatability issue.
