Mendel vitamin-less Y-carriage

In the spririt of the original Darwin this is a Y-carriage that uses virtually no vitamins other than two threaded rods and some machine screws.

The rods are just off-cuts from the lengths you use to build your printer so they won't even cost you anything.

Designed to take a standard Prusa-200x200 pcb-type hot bed which mount at 210mm centres (these heaters are cool at the corners so will be fine with a PLA printed carriage).

Utilises four of my unbreakable LM8UU bearing holders.
