This is a remix of CH35C0's Y belt tensioner for the A8. The geometry seemed a bit off for my setup and I also wanted to upgrade the idler. This version:
- has a lower center for the idler, more similar to the original Anet design
- has a bigger clearance so that you can fit an idler with guides like this one*, which is 18mm in diameter.
IMPORTANT: You should install a front panel brace if you plan on using a belt tensioner, like for example this one.
This is a snug fit on my A6, you might want to underdimension a tiny bit depending on your printer's accuracy.
The idler solves the issue of the light tapping from the belt teeth slipping into the groove of the stock idler and I think teeth might give it more stability. The idler has a 5mm hole, but it works fine with the original 3mm screw. I installed a M5 x 25mm screw, and it fits perfectly and keeps the idler really stable, so I've uploaded a 5mm diameter model as well.
I've kept CH35C0's screw and plate intact.

Rafts: No
Supports: Yes
Resolution: 0.2mm
Infill: 40%
Notes:
Screw and plate should be printed lengthwise if you want the threads to be strongest. However, I went for easy and printed the plate horizontally and the screw standing up. They seem to be able to deal with the torsion fine.
