3D model description

This device replaces the two bolts/cable ties mechanism for fixing the ANET A8 x-belt to the extruder carriage. It allows very quick tension adjustments without the need for complicated tensioning mechanisms.

This is a development of my previous device, which I recently found to break above the gripper releasing the belt ends. The previous version can be found here:

This design relies on gripping the teeth of the belt and no other mechanism for locking it in. There are slots to contain plenty of slack belt.

There are two versions: One uses an M3 x 12mm bolt; the other uses the existing M3 x 18mm bolt used in the original Anet A8 set up.

I have added another variant of the 18mm screw version for thicker belts as requested by PrinceOfCreation.

The grippers are really tight, but the belt will fit. Try feeding one tooth at the closest corner then feed remaining teeth that the gripper opens. Push the belt right into the groove. I used a 6" metal ruler which is ideal.

This was made to fit my 2016/17 Anet A8. It may not fit newer models.
