Prusa i3 Adjustable Y-belt Tensioner & Holder

thingiverse

Introducing two versions of this design: one for i3 printers with LM8UU bushing holders and another lower-profile variant without a holder, both compatible with T2.5 belts. An update from 15/06/14 includes zip tie holes on the top, thanks to RegionX's suggestion. The GT2 version is now remixed, as of 20/11/14. To install, you will need 2 M3x25 or 20 screws and nuts, along with 2 M3x16 or 15 screws, washers, and nuts to attach to the build plate. Don't forget about the essential 4 zip ties. Be aware that smoothing out the sides may be necessary for a smooth fit, and drilling holes in the upright piece is required. Note that the shorter i3 rework version has a tighter profile; this tensioner is longer than the original. To avoid belt cutting mishaps, ensure you're satisfied with the results before trimming the belt.
