Anycubic i3 Mega Hotend Overhaul

Anycubic i3 Mega Hotend Overhaul

This overhauled hotend housing allows you to see the printhead easily, allows for adequate cooling of the heat sink, hides all of the wires by moving the plugboard behind the x-carriage, and also has a modular part cooling duct that can be changed if you don't like the current design.

All parts shouldn't need too much help from supports. The parts are oriented in the best possible way for printing. Exercise your judgment when adding supports.

Foreword:

Make sure you read the directions before you start this project so you know what you're getting in to; some parts of assembly can be very difficult and frustrating. Needlenose pliers and a small mirror may be of great assistance.

This modification will cause the printer's hotend to be a little off center. Remember to add an origin offset of X = -2.6mm and Y = -3mm to re-center all of your prints.
