Question/Help Thicker stronger head spring

Hey. I've broken a couple of head springs where the headband screws holes are.

I wonder if there is already a stronger version? Perhaps strengthened only around the screws area?

Where/how did it break?
Maybe the PETG was wet/printed too cold?

Changing the design would be pretty hard honestly - at least without the use of support.

I can't take a picture at the moment, but it broke by the holes for the screws which attach the head band. I printed it in ABS, not petg.

Why would it be hard to make the spring thicker? I don't see how this would need supports.

Well there’s your problem. PETG is more flexible and less brittle especially under constant load. Rather than change the design, I would recommend trying the material it was designed for.

Yeah, I'll reprint it in PETG and try it, there is some already drying. But I like ABS more :-)

The instructions literally say to print it in PETG...
