thanks for your comment - I’m suprised how many people have found this useful for other purposes- it was to go on the back of a bird feeder I printed but I shared it when I used it d for a flexibility test myself to see how thin I’d need to make pla before it became too brittle!

thanks for the rating and comment - I printed this as a backing and just guessed the thickness but I’ve found it really useful on loads of random things - particularly when I want to use something flexi. maybe it found a thickness sweet spot relative to the diameter!
