Anycubic i3 Mega Lightweight Hotend Housing

Prints (0)


This hotend cover is based on the following design:

However, I redesigned the hotend cover quite a bit. Most important features of the cover:

  • Lightweight: reduces ghosting and costs less filament to print
  • Is compatible with both the stock parts cooling fan and heatsink fan
  • Can be mounted with four M3 nuts and M3 bolts, a link for which can be found below
  • It is much easier to reach the hotend distribution PCB

I suggest printing this part at 100% infill and with tree supports.

Depending on the accuracy of your printer, it might be necessary to sand/file some parts of the hotend cover, in order to make it fit perfectly.

You can buy the needed hardware from the following link (affiliate): Bolts & nuts

You will need to use support for this print. I would recommend using tree support (experimental feature in Cura, or add it using Autodesk Meshmixer), as this makes it very easy to remove the support material after printing.
