Could you please publish a 3D model of the 3DChameleon Mk3 B and C parts?
I printed the files linked below and upgraded from Mk3 to Mk4.

The notching of the PTFE tube is an interesting idea. However, it wastes PTFE tubes because they easily tear from notches. Also, if the tube is not notched well, the hole will be narrow and prevent filament loading. On the other hand, using of brass compression fittings is more costly, but allows for smoother filament loading than notching.
In case Mk3 B and C parts are damaged, it would be appreciated if you could publish the files of them.

In Your 3D Chameleon Creations
I wrote the instructions for upgrading from Mk3 to Mk4 Pro (added OLED only) in my blog, and uploaded a simple demonstration of the Mk4 Pro on YouTube. I hope they help everyone (especially macOS users). Note that my blog is written in Japanese, so please use a translator like DeepL or Google translate.
In addition, I designed a mount for attaching 3DChameleon to a metal rack, and uploaded STLs to Printables. I would appreciate if you download and like them.

Thank you.

I installed 3D Chameleon Mk3 on my Prusa MINI+ with the help of YouTube videos and information from Printables. The mode is set to Direct Drive Mode.

I have tested loading with PETG filament @220-250℃. It feeds it smoothly until the filament reaches the nozzle, but once it reaches the nozzle it is not feeding the filament well, perhaps due to weak tension in the gears and bearings. What should I do to solve this?
E-step is set to the recommended value of 152 for this thread (and for other settings as well).

Any advice would be appreciated.
