Anet A8 Belt Tensioner X-Axis

Anet A8 Belt Tensioner X-Axis

This Anet A8 X-Axis belt tensioner has many features that set it apart from the other x-axis tensioners. This design has about 1000hr of print time on it now. It is still working well.

• M5 nut traps and bolts are used to improve the accuracy of the clamping force.
• Reduced part count - removed washers with raised pully mounts
• Deep wells were added to hide the bolts after the belt is taught.
• Increased Length of stabilization Arms
• Improving the look and feel of the part.

The nut traps are very tight. Position the nuts in front of the traps and then use the 12mm screws to draw them in.

When the belt is taught - thread lock can be added to the nut/bolt to secure it in place.
