Replaces metal housing of Anycubic I3 Mega printhead. Improves printhead clearance, airflow, and visibility. New cooling duct is sized for a standard 5015 sized blower. Cooling duct is sized and aimed for a v6-style hotend (shorter than the v5 hotend that comes with your Mega).
Needs the following hardware for mounting:
-2x M3x10 cap screw, 2x M3 nut (mounts sides to top of printhead)
-2x M3x16 cap screw, 2x M3 washer, 2x M3 nut (mounts sides & duct to back of printhead)
-1x M3x20 cap screw, 1x m3 washer, 1x M3 nut (secures cooling fan to duct)
Print in PETg or ABS for heat resistance.
Changes the 'home' x-position to -3mm from -5mm. This can be accommodated by adjusting the home position in firmware. Also reduces the far x endstop by about 10mm. This can be fixed by adjusting your firmware or slicer settings, or possibly by flipping the extruder mounting bracket (I'm not sure if this will give enough space because I have a differently sized extruder motor from stock)
Still a work in progress (particularly the duct), so let me know if you have tweaks.
