I am prototyping a workshop idea for easter. Its fun but trying to center and egg is a challenge 😅 I think I have to 3D print an adapter or even the hole egg 🤔 Also attaching the egg to the motor is hard. If you use glue, the egg breaks when you take it off. For my prototype I glued a small magnet to the egg....
