AM8 reinforced Y-axis tensioner

AM8 reinforced Y-axis tensioner (by blv)

This tensioner was designed especially for my next
AM8 mgn12 mod i am working on right now.

* The block is wider and more stable.
* Tensioner much more wider and 25% stronger.
* added more flexibility with the tension length

You will find instruction, print orientation and Quick assembly guide down below.

Please notice:
This is a highly stable tensioner without any "dancing" motion, It designed to eliminate any vibrations from the belt. Th
