I wondered what a space filling curve might feel like to play with, so I made this. Even though it kind of looks like a space filling block, it is indeed just a single curve looped in on itself and thus can be printed in spiralized vase mode.

I printed my model with Prusament PLA and vase mode on an MK3+. I turned off the elephant's foot correction because it messed up the first layer for a print of this type.
