Heatbed cable cover deforming
I've recently been printing a lot of ABS, and noticed that the heated bed cable cover has started to warp from the heat.
This hasn't happened for hundreds of hours of printing PETG at 80c bed temp.
With the recent ABS printing I have been running the bed continuously at 110c for a few days. I checked the connection and it seems ok, no discoloration or anything and lug screws are still tight.
Is this expected due to increased current from ABS bed temps? I'm planning to reprint the cable cover in ABS and carry on as usual.

Come to think of, with a heatbed at 100C or higher isn't surprising that PETg parts in close contact with the bed start to deform. after a while.

As I've been printing a lot of ASA lately, after reading your post, I inspected the heatbed cable cover of my MK3S+. Sure enough it's also deformed, although not as much as yours. Thanks for the heads up.
Good idea to print the part on ABS ( or ASA ) and probably the bottom part of the cover too.

Yes, I have taken this opportunity to print a 60deg cable cover since my i3 is in an enclosure (already broke a thermistor wire when the cable kept bumping against the back wall).

The other part you may want to consider reprinting is the PINDA holder. After printing a lot of ASA, I noticed my live z was increasingly off, and sure enough, the PINDA holder was warped.

Great idea. Funny enough, my printhead currently is a mix of ABS and PETG. Unfortunately the part that happens to hold the PINDA is...yes PETG 😊
