mbe Printhead v1.0 - Anycubic i3 Mega S Head with Dual Part Cooling Fans

thingiverse

This is the first and the most important upgrade for your Anycubic i3 Mega S as it dramatically improves cooling and thus PLA print quality. It mounts on the X carriage mounting plate, so no disassembly of X axis is necessary. This is important, as re-assembling the X axis rods for trouble free operation requires precision, tools, and knowledge. It re-uses the standard head PCB, so the connections are simple and elegant. As a bonus, you get an adjustable X axis belt tensioner, part lighting LEDs and all of this in a lighter package than your stock metal assembly. A magnetic bed probe will be posted soon as a separate thing, but will require a firmware upgrade and will only fit ABS prints due to available elasticity of ABS for press-fitting magnets. The head is designed to be easily exchangeable (to one with a different nozzle size, for an example). For this you only need to undo the stock head connector and unscrew two mounting screws. The alternative head requires its own fans and a PCB, though. The fan shroud visual was inspired by the great work of what has now become Apogee head on Orbiter Projects page, but was designed from ground up for easier printing on an open printer and for extra future features required.
