UPDATE March 22/20
Printed a replacement for my printer: https://www.thingiverse.com/thing:3571659
I noticed the end pivoting up and down on this thing, which causes inaccuracy in the y-axis. This updated design works much better and uses less plastic.
UPDATE September 29/17
Added Y-Axis 2.0 for those that don't want to take apart their frame. Fits snugly over the 2020 aluminum.
Y-Axis Belt Tensioner for the Hictop Prusa i3 20x20 aluminum frame version.
Uses existing hardware:
-Bolt and Bearing combo
-4 m5 nuts
-4 m5 x 8mm bolts
-2 m3 nuts
-2 m3 x 20mm bolts
Print Tensioner at 35% or higher, the guides can be as low as 10%, it shouldn't really matter.
I would recommend at least 3 outer perimeters on the Tensioner also.
