Anet A8 Belt Tensioner X-Axis This Anet A8 X-Axis belt tensioner has numerous features that distinguish it from other x-axis tensioners. With over 1000 hours of print time, this design continues to perform well. Key Features: • M5 nut traps and bolts are used to enhance the accuracy of clamping force. • Reduced part count - eliminated washers with raised pulley mounts • Deep wells were added to conceal bolts after the belt is tightened. • Increased Length of Stabilization Arms • Improved look and feel of the part This design is compatible with https://www.thingiverse.com/thing:2821719. The nut traps are very tight. Position the nuts in front of the traps, then use 12mm screws to draw them in. When the belt is tightened, thread lock can be added to the nut/bolt to secure it in place.
