Ah, good to know! This is one that is compressed, held in compression for 99% of it's life, so we'll see what happens.
(that said, I went ahead and purchased this $12 kit: https://amzn.to/3yaXT48 )

Ya Feckin turn coat, you do a great job making the O ring and getting it to fit and work , and then you go buying substitutes, have you no faith in your ability at all..

You would you go and Feck off, your starting to sound like my Wife, and if you want to know I am getting there, but I still need a few more new pieces before I make all the changes to my other CR-10, then I’ll be cooking with Gas..

I just printed this phone case on my Ender 3 pro (standard Bowden setup) in Sunlu TPU. Bridging and overhangs worked out quite well. Took about 7 hours at 15mm/s. Sliced with SuperSlicer, 2.5mm retraction, and using pressure advance and Klipper firmware.

WOW! That's incredible! Looks PERFECT!

Ironically, just last night I was thinking "I should try to print a phone case for my phone. It would be a cool conversation piece!"

... but it's a bit daunting considering how much bigger, longer, and more complicated it would be. Especially since I'm not using anything fancy like Klipper, etc.

I don't know how much Klipper/pressure advance helps but I think at these very slow speeds not much - so I reckon you'll be ok (and you can use linear advance in Marlin in case that helps). I'm just using the standard plastic extruder, bowden tube and hotend. It works perfectly at 15mm/s but I'm resisting the temptation to go faster.

An update to the gasket I printed!

Seems like it's been working fine in my GF's sodastream.

Well, I found the original gasket and decided to replace the one I printed. Here's what it looks like (now) for comparison:



As you can see, the TPU one did compress and lost it's ability to "bounceback"

If you stretch the TPU ring a lot it won't shrink back to the original dimensions.

... pretty much exactly as expressed by @Artur5 !
