Prusa i3 - Upgraded X-Carriage for 15 x 45mm linear bearings

This is a prototype X Carriage for a Prusa i3.

It has been designed to accommodate 2 larger linear bearings to greatly reduce play in the carriage.

Hole centres for linear bearings: 45mm
Hole centres for Bowden type hot-end: 22mm

I am currently in the process of printing and optimising print quality for this part.
Updates to the design will come in time as it has yet to be fully tested!
