3DChameleon Mk2 Ender 3 CR-10 Style Mount
Description
This is an adapter to allow a PTFE Tube to connect to the Ender 3 / CR-10 style extruder using a PC4-M10 connector. This allows the 3D Chameleon to automatically load and unload the filament. (Note, it adds about 2mm of height to the extruder, but the stock screws are long enough to still allow a good connection to the motor. On some machines, like some the Ender 3 V2s, you might need to rotate the extruder so the filament input is on the back to clear the screws holding the Z nut to the metal plate. In that case, the filament will come out towards the front of the printer. Added the second version of the mount which allows for the newer style extruders to clear the Z lift-nut screw as well as allowing the extruder arm to pivot further. Please note: The PTFE tube should extend all the way through the PC4-M10 connector and be cut flush without output side to align it up with the input side of the extruder. If it is not aligned up, it will cause a point where the filament can jam. Use a straight cut (with a sharp razor or PTFE tube cutter) and not a pair of side cutters to ensure that the edge is perfectly round and not crimped or crushed. (If you look very carefully at my picture of me holding it, you can just see the white PTFE sticking out of the top.)
