I’ve just made a new version of my nozzle cam for the M5C, and I’m really happy with the improvements. It’s way easier to mount now, and it looks a lot better too. I also got rid of the two slots for extra LED lighting since the endoscope’s built-in light usually does the job just fine. Overall, it’s a simpler and cleaner design that still works great!

For installation, you’ll need to unscrew the whole extruder head, unfortunately. There are 4 screws on the back side, and once they’re undone, the head comes loose. Then you can snap the part onto the back of the extruder head. Just make sure to align the notches in the part with the notches in the head. Once that’s done, screw the extruder head back on, and you’re all set!

One important note: make sure to print the part in PETG, not PLA. I tried PLA at first, but it snapped when I tried to snap it into place since it’s more brittle. PETG also has a higher melting point, which is important since the part is really close to the hotend.

I did notice that the sleeve on the hotend blocks part of the camera’s view. If I took it off, visibility would improve, but I’m concerned it would weaken the arms holding near the hotend. It’s not a big deal, but having a big green block on top of the frame isn’t the most aesthetically pleasing.

I wanted to make it more modular and easier to mount, but I just couldn’t think of a better mounting spot. The back seemed like the best option for now. If you have any suggestions, please let me know—I am intrigued to hear your opinions!
