Anycubic I3 Mega X axis tensioner

thingiverse

This is a X axis belt tensioner for an Anycubic I3 Mega. Two M3x4x5mm thread inserts are required and two M3 bolts. The bolt which mounts to the pulley should be a countersunk head screw, to save space.You will need to drill an additional hole in the X carriage sheet metal component (see image).Print the part with high infill and with build plate adhesion + support.I did not test it in the long term, but seems to work so far.
