Out of curiosity, what printer would they be using for something like this? I've been considering getting a 3D-printer for a while, but I don't know enough to decide which one to get.
I did get the Prusa I3 MK3S and it's just incredible, I'm astounded by the quality of the prints and the printer itself. I've already designed a number of parts in Fusion360 and printed them with a variety of different filaments (Flex, PLA, PETG) and having a lot of fun creating things!
