This is the first time I've had this much issue removing a print.
I knew it would stick fairly well on the textured PEI, but this was a whole new level. A bit surprised I didn't peel it, to be honest.
I'm leaning the same direction as those people: Buying a stick and keeping it around for those few times I do use TPU. PETG and PLA is still 98% of what I print, and they both come off easily on textured and PLA easily on smooth.
The question I'm stuck with though: Textured with glue or smooth with glue for TPU?
