**NOTE:** X-MOTOR.STL and X-IDLER.STL are made for 22mm spacing
**UPDATE 15.5.2016**
- moved X-stepper mount point 5mm to left for 21mm version (X-MOTOR_21mm_WIDER.STL)
**UPDATE 14.2.2016**
- made parts with 21mm spacing for Geeetech i3 pro c
**UPDATE 29.12.2015**
- I had identified wrongly the idler bearings my printer came with. They're F693ZZ, not F623ZZ. With latter GT2 belt could not move freely. I have modified the clearance of the belt tensioners arm part so that both bearings should now work.
- Updated belt tensioner arm part is added as own file for those that have printed the complete set before.

X-axis with fixed X-endstop and finger adjustable belt tensioner. Nothing new compared to already published (like ffleurey's
thing:169636 and jkoljo's
thing:372056). It's just this smooth looking design I like and wanted to share it.
Note that there's no spesific Z-endstop trigger point as I prefer inductive proximity switch (mounted with
the extruder).
**The distance between Z-axis's smooth rod and leadscrew is not same in all Prusa i3 versions.** The kit I bought from Aliexpress.com is having 8mm acrylic frame and designed with 22mm distance but it seems that 17mm is more common. Also in Geeetech I3 X the distance is different, 27mm.
- I have made necessary modifications and now there's X-motor and X-idler for 17mm, 21mm and 27mm distance too. Please inform me if the design has any faults.
- stepper motor mounting point is moved 5mm to the left in X-MOTOR_27mm (Geeetech I3 X)
GT2 belt ends should stay in place without zip-ties. My printer is fixed in enclosed cabinet so belt removal is easier and doesn't require removal of X-carriage.
