As others have pointed out, you're describing nonplanar printing. If you really want to have fun you should look into 5 axis 3D printing, which can not only do the nonplanar stuff you're talking about but also tilt the head to print features onto the side of the part and take advantage of different layer orientations, though I'm not sure anyone has mixed nonplanar printing with 5 axis yet. As a bonus, Prusa is working on taking advantage of the tool changing capabilities of the new Prusa XL printer so that some parts of the print are done with a different size nozzle and layer thickness than others, and even different materials. edit: Just remembered Stefan from CNC Kitchen also wrote a python script to warp vase mode prints so he could use nonplanar printing to print curved tubes. https://www.youtube.com/watch?v=0XaaUXOwzTs https://www.youtube.com/watch?v=0XaaUXOwzTs
