Anycubic i3 Mega Y belt tensioner
thingiverse
I scored a Y belt tensioner for my i3 Mega on thingiverse, but it called for a small bearing I didn't have on hand, so I fabricated one myself using an 8mm x 22mm x 7mm regular skateboard bearing. Before installing it, ensure your extruder is properly calibrated and the first layer's flow rate is set to 100% - otherwise, you might encounter issues inserting the screws.
