Prusa i3 Updated X-Axis Motor and Idler Ends

thingiverse

I wanted to update my Prusa i3 Hephestos's X Ends and I also like the way that the X Ends from the Infill 3D i3Redux look. http://www.thingiverse.com/thing:371842 https://infill3d.com/home/37-x-motor-mk52.html https://infill3d.com/home/36-x-idler-mk41.html So I combined the current functionality of the Hephestos with the looks of Infill 3D. Features: 1) Belt Tensioner. 2) Anti-backlash on the Z-Axis. 3) Opto sensor mount for X-Axis home sensor. 4) Secure clamping of the X-Axis slide bars. I incorporated a belt tensioner similar to the Hephestos design. I'm using Opto sensors on my printer and did not like the stuck on look of the sensors so I added a mounting point for the X-Axis home sensor to the motor end Anti-backlash is built into both X-Ends. I added clamps on the X-Axis slide bars to lock them in place so the tensioning the belt would not distort the Y-Axis by pulling the X Ends closer to each other. I will still create new cable chain mounts for the motor end. As always, drop me some comments if you find errors or have improvements in mind. Update 2015-07-13: Uploaded source files in step format exported from TurboCAD. Unable to test the step files integrity as I can only take them back into TC. Update 2015-07-24: Added a slot on the motor end to reach the pulley grub screws
