Anet A8 Improved Y-Belt Tensioner Bar

thingiverse

I love the Y Belt Tensioner by freemark! It has two screws for Y Tensioning. This allows for slightly angling the pulley left or right to line it up just perfectly. I added some thumbwheels, washers, and lockwashers to lock it all down. I had a spare piece of plastic that I used between the frame and screws to prevent damage or cracking. However, I knew there had to be a more elegant solution. This Y Belt Tensioner by Audiogod is pretty sweet for those that prefer the one center screw adjustment (doesn't allow for angling the pulley just right). If I did prefer that method, I would definitely print this one. That said, I transported over the bar Audiogod developed which was very nice and spreads the force out over a larger area. It was a bit too big for this mod, so I cut it down a bit to allow the bracket to slide in and out without rubbing. Here it is.
