Hello
I Just have couple parts from my 3d printer so I've built a toy :) It's usually spins for 1min, maybe heavier one will spin longer. I'am looking forward for yours results.
to build launcher u need:
-gt2 belt
-two 624 bearing
-m4x40 bolt ant nut

whole toy was printed in pet-g with 15% infill, without support
