i3 Plus Y-Axis Tensioner (Wanhao, Cocoon Create, Monoprice, Balco etc)

Edit 27/08/2018: Added versions with 0.2mm extra clearance around entire loop sections for those struggling to get original to fit. Opening is same size to keep clamping force of original intact. Number of spacer plates have also been added to sit between tensioner and mounting plate. Here's a Y axis tensioner I redesigned specifically for the i3 Plus and clones. It took significant amount of texture out of my prints and got walls looking much better. I remixed AdamBath's design on Thingiverse (thing: 2368192) to use M4 hardware that I had on hand. Main differences with my design: - This one is 1mm shorter - My version uses an M4 20 or 25mm screw and a standard M4 nut - Both belt loops are on the same plane - Redesigned guide pin There is 0.2mm of clearance around entire guide pin so depending on your printer's capabilities, you may need to shave off some material from pin to get good fit. Materials Required: - 1 M4 20 or 25mm screw - 1 M4 standard nut (not nyloc) - 1 'Base' piece - 1 'Slider' piece - A few small zipties - Small piece of foam I also installed this brace for the idler pulley a while ago and I would suggest using it to cope with extra tension on belt: https://www.thingiverse.com/thing:2561371
