Anet A8 X Belt holder and tensionner

thingiverse

Loved the original design with the tensionner but it didn't fit my (probably old) Anet A8 with the black bearings blocks (not the grey ones): the holes were a bit too low and the belt was touching the holder. I've changed the body to make it a bit smaller and thinner. I did not change the tighter, even if the belt is still touching a little bit but a little bit of sanding is enough.
