JG aurora a3 y belt tensioner
thingiverse
Y axis belt tensioner for the JG aurora A3. I had a bad time when I first made this printer because it was hard to get tension, and my circles turned into ovals. After installing this, it instantly fixed the problem. Lots of room to adjust as well. I also included a stabilizer if you really want it to be stable, but after putting on the parts just in the picture it worked perfectly fine, and it's probably useless. I recommend printing this with the belt mount that I have also made, otherwise your belt could come off easily
