So this is a prosaic print for a Hall of Fame, but bear with me...

About two years ago, I bought a new Maytag clothes dryer and its extended warrantee. We have a big family, and the machine runs probably 3-4 times per week. As with many post-pandemic consumer goods, I noticed early issues with quality and reliability - including the need for a full belt swap within 6 months of purchase.

Sadly, Maytag had turned to junk long before the pandemic arrived.

Also -- one serious question came to mind that demands an answer :) --- how the heck did you achieve the radiating "texture" on those knobs.  I've seen sheets with carbon fiber and random star textures, but nothing with the texture you've achieved.  Help out a curious mind here, please???

In the Prusa slicer go to Print settings -> Infill -> Top Infill Pattern and select  Octogram Spiral.

This works best with metallic filaments, and is my go-to for making a flat surface more interesting without extra design work ;-)

ps: while printing a new knob deserves kudos, a trip to the autoparts store and purchasing a few hose clamps of the proper diameter also work as repairs.

Normally, isn't there a metal band around the knob shaft that provides the strength and resilience?  At least, that's what I usually find on such things.  Maybe you just got an incomplete knob.

Yes, there is - and this metal band was present on the knob (actually, all of them that I replaced). The metal band holds the nylon shaft that is on the machine selector, and is supposed to provide a snug fit against the ABS knob. My knob cracked around the metal band, which was still intact.
