Y-Axis Torsion Box for Prusa

*****UPDATE 2015 -> If you are here because you have Y-axis lash, and your printer use T5 belts, try to replace it by GT2. I had T5 before, lots of lash, now GT2, no lash, no lemon shaped circles, perfect sizes.

I found this motor holder and it worked so well, that I decided to go further and make it completely unamovable.
You will need:
- 7x M3-40 screws
- 3x M3 nuts

Hope it help you to fight against the lash!
*Made two versions, WITH & WITHOUT Belt tensioner inside.
