I decided to give this tealight thing a try using a really nice Sapphire translucent PET+ filament. I was reluctant to print it because the high temp necessary and I have this ebay special jhead all metal hotend with a ptfe liner. It probably fried that liner (haven't taken it apart yet to see) but the print came out fantastically.
this was printed on my DIY prusa i3 at .15mm layer, .4 shell, with spiral mode on.
pictures don't really do it justice and I haven't really nailed down the best way to photograph these things.
So I'm not sure what I should have expected from this filament. Should it be smooth as glass ? because it's rough kinda but in a neat way. Interesting texture. The filament leaves a lot of cob-webs I tried to clear them with a lighter but that kinda blackened the surface so that's not a good idea... Thinking a small wire brush next time.
