3d Chameleon Extruder and Switch Mounts for Anycubic Mega X

thingiverse

I wanted to try the 3d Chameleon dual color kit on one of my Anycubic Mega X printers. The 3d Chameleon is a very clever devices that lets you retrofit a single extruder printer to use 2 extruders, but 1 nozzle. Since the kit is heavily geared towards Creality users, it looked like I would either need to make some permanent modifications to my machine, or design some printable brackets to mount the extruders and the switch. My printers are in a shelf that leaves very little vertical space, so I mounted my extruders on the left vertical arm (instead of the top horizontal beam). However, if someone is interested, I could redesign the vertical arm brackets to work on the top beam. I made a bracket that would fit on the vertical arm, and then put a T-slot channel in it to use the provided mounting hardware. Printed 2 of them, and secured them with a little bit of double stick mounting tape. It could also be used to mount any other T-slot accessories that are commonly used in 3d printing. The switch bracket took me the longest. It mounts where the Anycubic stock extruder mounted, using the same screws and mounting holes. it wraps around the other vertical arm, and travels up and down with the gantry, so that it can be pressed to change extruders. I marked this a work in progress, because I'm still tuning my Cura profile to make this all work seamlessly. I'm getting closer to that though. Once I get it nailed down to where I'm happy with it, I'll include a copy of a project saved with those settings, etc. I've had to change it a fair amount from the included profile for the Creality machines, but I'm getting really close to having it working for my Anycubic Mega X The two printable brackets are NOT works in progress, they are pretty "final". I'm pretty happy with them. Supports not needed for the vertical arm brackets, but they are needed for the stop switch. Printing so the layers run horizontally through the pieces is fairly important for the strength of the object. I printed them in PETG, because I have the printers enclosed, and worried that PLA might get close to the glass temperature if I was printing something in ABS
