Fiberlogy MattFlex has been awesome!
Also thumbs up for Add:North. Been really consistent with both PLA and PETG.
Filamentum is also really nice.

Yeah they have properties that make them desireable, like making them easier to print.

I just can’t get myself to play with them knowing the air and my fingers will be full of microscopic sharp particles. Maybe they do nothing, but I’d rather err on the cautious side.

Being downvoted doesn’t make you any less right.

That being said: I won’t be buying Bamboo again myself. The H2S is awesome, but my next machine will be RatRig/Prusa (European)or maybe even Snapmaker. Still waiting to see how they hold up after some more time, and if head swappers are better or worse than toolchangers like INDX.
