Anet A8 X-belt tensioner for GT2 pulley

I printed the [Anet A8 improved X-belt tensioner by freemark][1] and needed to customize it a bit as I wanted to use a toothed pulley instead of the stock one.
Furthermore I felt as there was a size mismatch for the nut. I would have needed a M4 to fit but an M3 screw.

This was designed for a GT2 16 or 20 tooth pulley combined with M3 washers on either side.

For installation instructions read the files supplied by with [freemark's thing][1].

A big thank you to [mtepedino][2] who provid
