i3 Mega / Mega-S fanbox

thingiverse

These are to replace the factory fan box around the hot end. The left side adds 2 mm of additional clearance between the cooling fan frame and the heater block. It also has a circular cutout that makes room for the fans metal lip and allows it to sit flush against the part. This is important if you upgrade to an E3Dv6 as the heater block is wider than the Anycubic factory version which causes the cooling fan frame to butt up against it. The front piece aligns perfectly with the notch on the side piece. Original screws can be used, but you will need three 3mm nuts to tighten things down. You can use a few additional 3mm nuts as spacers when attaching to cooling fan, or cut the original plastic spacer down to fit the gap.
