X-Belt Tensioner (Anet) A8

thingiverse

I bought an A8 on Amazon and later found out that it was just a China clone. When I went to reprint some things, I realized that the dimensions no longer fit, so I took matters into my own hands and tinkered with the things myself. In general, I stuck to the dimensions of the other model, but I did reduce the width of the guides so they would fit into the recess of the right X-mount. The recess in the casting is 7.6mm wide, while most X-Belt Tensioners have guides that are 8mm wide. In my case, the guides are a bit narrower at 7.5 mm. I drilled holes that are 3 mm deep and intended for M3 nuts and bolts. Maybe it will help someone else who is dealing with the same problem.
