Ah, very cool. I've always wanted to visit there. Greetings from across the pond. I'm one rare American that prefers metric over imperial. I can definitely see an armpit hitting 100 degrees Frankenstein on a balmy summer afternoon though. lol. I for one prefer it a little cold. My wife however.. Hmm.. My shop is in the basement though so it stays a little chilly in there all year.By flexible PLA do you mean something like a PLA+ that has more flexibility than regular PLA? If so then yes. My favorite is eSun PLA+. I haven't yet tried anything with TPU though. The CR-10 V2 uses a bowden extruder so I'm not sure how well it would work with it. The Qidi uses a direct extruder and the manufacturer claims that it'll run TPU, but I have as yet not been able to verify that.
