Updates:
2021-08-26 Added a repair part if the cover snaps so you don't have to print off a whole new cover. Requires an additional M3x8 nut and bolt, and probably a longer bolt to go through both parts and through the axis plate.
Minor remix of the original v6 to help prevent the thin attachment from snapping.
I was working on the hotend a lot and the one screw attachment kept snapping meaning another long print for a new cover. I've remixed this to help prevent this from happening.
It's a bit less convenient to attach and remove (you have to unload the filament and pull the bowden tube from the hotend) but it is less prone to breaking now.
Many thanks to the original designer for such a great replacement/design.
