Hello! Is it mandatory to replace the Heatbed Cable Cover 60 Degree when we have an Ikea closure. The cables rest in the polycarbonate at the back of the box, when the bed is in the rearmost position?

    I printed them from Prusament PETG, but I have to disassemble a lot of things to install them, and the power supply is out of the box and the cables are very short. The space I've chosen for the printer with the box is tight and very laborious to work with, at least for now. In principle, the original part is cast from PETG or from ABS, ASA??

Thank you!

It's just a PETG part.

RE: Prusa MK4 90 Deg Heatbed Cable Bracket for IKEA Enclosure

Yes, the original Prusa cable bracket is PETG but I strongly recommend printing it from a filament more heat resistant ( ABS/ASA/PC) if you print often with the bed at temperatures higher than 80C. Take into account that the bracket is in close contact with the edge of the bed and PETG filament starts to loose rigidity above 70C. I had to replace mine after printing a bunch of ASA parts, because it was sagging visibly.

With the original straight cover, the cable bundle will hit the back of the enclosure when the bed slides to its rearmost position. So unless you move your printer forward so much that the LCD display sticks out, you should replace it with a 60 degrees or more cover.

The original cover is made from PETG. However, I had it melt on two of my Mk3S after a year or so, so I replaced it with one I printed with PC-CF (ASA/ABS would be fine two). If you only intend to print PLA and PETG, a PETG cover would probably be okay but I've printed PC-CF and ASA as well so the heatbed gets heated up more.

Thanks everyone for the replies! I think I understood. After I purchase my ASA I will print a new set, but I won't be in a rush.
