Yes. It's still in Alpha testing. i haven't even printed all the pieces yet, but here is what it's going to look like, and the parts. Basically this will require another hole in the Y Idler Endplate, a new bolt and nut, and 4 newspacer thingies. Optionally it will also have a mount for a Y maximum endstop and a replacement belt mount with the Y Maximum Endstop Target. The theory is that the new bolt goes through the Y Idler end plate in the new hole, and into the new Nut in the idler block. Turning the bolt tightens or loosens the idler. The idler is prevented from rotating by the 4 spacer thingies. I've used a similar design to this on my slightly modified AO-10x for years and it works great. This also slightly shortens the belt path, which always improves accuracy (less belt, less potential belt give.)
There will be a thread with pictures and part lists and whatnot as soon as I go get the parts and verify that everything fits. I wouldn't reccommend printing this one yet unless you want to help me test it, as it is not a tested product yet.
