Prusa Steel Lead-screw x-axis

X-axis lead-screw system for prusa i3 steel or any other prusa styled printer with 17 mm between linear bearing and z axis screw

X-motor: has an integrated mount for a mechanical endstop
X-idler: has built in belt tension system, where the force is applied through the x-axis instead of onto the z-axis.

The tension system use M6 nuts and bolts, and i recommend redrilling all holes after printing and seating all nuts using a soldering iron.

Part of the design was inspired by the designes made by toolson, and it is compatibel with his z-endstop mount.
