I feel super bad about not answering a super silly question like what plastic did you use, so I am hoping if someone googles on even better uses this wonderful forum of information to get an idea what plastic to print, PETG is wonderful. No problems, ever. Ok that’s a lie everything has problems but it’s great. ABS works too , I have read , but I’ve never printed it. I do not get any type of compensation for this just hoping to help someone stay away from certain plastics who spend money to show up in search results instead of making quality products. The top one I use with black, white, blue, and red all look nice and greeeeat price. The bottom one is more expensive but buy 10 at a time then it’s not more expensive anymore! I’d love to hear others opinions, I’m always willing to throw some new plastic on my CREALITY ENDERS
