About this 3D model
The PA-CF version of my PETG phone case with Quadlock for Samsung Galaxy Fold 5. This needs to be printed outside the AMS due to PA-CF abrading the AMS, and with hardened steel nozzle. I use PETG as support for PA-CF which has worked well. I recommend using a glue stick on top of the PETG layer prior to resuming the print with PA-CF, to improve reliability of the next layer. You will need to modify your G-code since MakerWorld strips this, but it is essential to allow easy filament changes outside of the AMS. Copy the below into the “Change filament G-code section” of the “Printer settings”. Replace anything there before.
