Belt Tensioner For Nema 17

This is a belt tension that I am using on the Z axis of my Tron X5SA printer. Other parts you should need if you want to do the same (aliexpress or other):

-Various M3 bolts and nuts (many can be found as extras in your 3d printer kit)
-M3 slider (used on fixed side of tensioner
-1140 Tooth GT2 Belt
-50T GT2 Pulley
-Hard drive bearing

Of course other pulleys and belt lengths will work, however you may need to change the tensioner arm to suit.
