Simple belt tensioner for the Rook 3D printer,
First version needs 2 m3 nuts and bolt,
One nut for achting as the counter nut , and the second to not drive the screw in the motor mount.
update :
I made a bit longer version so with a bit more clearance at the back and with a heat insert.
Heat insert used is m3x5
Hole in part for insert is 4.6mm in diameter.
Needs a m3 nut to prevent the bolt driving in the motormount.
When I tension the belt I fasten the 4 stepper screws and release the tensioner screw so it's not pushing.
