This is a remix of Logan Royer's design. He took Prusa's Y axis design and modified it to fit on the Anet A8 (A6 won't work). It's a brilliant
...Plus design, and I tweaked some things, so I'll only be uploading what I modified. The belt tensioner and endstop piece can be found in his post: https://www.myminifactory.com/object/anet-a8-prusa-style-y-axis-upgrade-50267
Note that I have a diagonal reinforcement piece in the pictures since I was installing that upgrade next.
To further reinforce your frame and compliment the new axis, I strongly recommend printing these:
