Just a simple Hopter that will fly. But not fly to well.
The idea is come from an animation, lol.
So, I try same model with different sizes, some scale works some don't due to bad dynamic balance. Also, sometimes if you reduce weight on rod, it will fly weirdly. So the current is somewhere I can get fly well, but not to much lifting force. The handle is long enough you can conformtably play it.
Place on build plate like this, it should print without support and brim.
Makesure you clean the build plate well before you print.
