Anet A8 Y Belt Tensioner

There are quite a few belt tensioners for y axis of the Anet A8, but I was not realy satisfied with them. So I decided to create my own design.

The tensioner is attached to the main frame of the printer. It's basis is fixed and shouldn't move at all. To stiffen the frame I use this thing in addition: https://www.thingiverse.com/thing:2152976.

You can use some spare 30mm M3 screws to tighten or loosen the tensioner. Movement is about 5mm. The position of the lever can be adjusted precisely
