i3 Adjustable Y Belt Holder for GT2 & T2.5 I decided to combine the designs of the Prusa i3 Adjustable Y-belt Tensioner & Holder and i3 Rework X-Carriage for GT2 & T2.5 together into a new Adjustable Y Belt Holder. You can attaching T2.5 or GT2 belts much easier and without using zip ties and of course, adjustable. Ah don't mind the funky colors, I'm testing the new E3D Cyclops and had some Navy Blue (60%) mixing with a white (40%) to get a little blue. As you can see, not all filaments mix well. :) BOM: 1 M3x30mm bolt & nut and 2 M3x15mm or 2 M3x10mm to attach to build plate.
