X-Axis revision with belt tensioner

I made an X-Axis revision with belt tensioner and bearing clampings. It is inspired by the bear mod x-axis but fits with the normal Prusa extruder. The x-axis is also much stiffer than the original one. Additional holes for m3 screws to attach a camera are also integrated.

All Features:

• Belt tensioner
• Bearing clamps
• End stops for the bearings
• Integrated holes for camera ect.
• Stiffer than the original X-axis

Compatible with:

• MK3 Extruder
• MK3s Extruder
• MK3s+ Extruder

What you need:

All screws an nuts of the original X-axis

and

• 4x M3 x 12 screw (ISO 4762) for bearing clamps
• 4x M3 Hex nut (DIN 934) for bearing clamps
• 2x M3 x 18 screw (ISO 4762) for belt tensioner
• 2x M3 Hex nylock nut (DIN 985) for belt tensioner
• 1x M3 x 16 grub screw (DIN 913) for belt tensioner idler (you can also cut a M3 screw and use it)

Tighten the screws of the bearing clamps carefully otherwise the bearings will take damage. The slit should not close completely.

If you get an x-axis error after assembling make sure the rods are pressed all the way in.
