This is a traditional bamboo copter. It's simple and prints in 23 minutes. I would suggest printing it on its side because printing it upright leaves the shaft very weak. TPU is too heavy and PLA is too brittle. I would suggest using Prusament PET-G. This model does require supports.

Settings:

0.25mm layer height

15% gyroid infill

Supports: On

Rafts: doesn't matter
