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.
This has been designed to work with https://www.thingiverse.com/thing:2821719
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.
