Planetary Gear Puzzle: A Challenging Brain Teaser It's a lot harder to crack than I thought it would be... Print 1 each. Print 3 of Planet 1 and Planet 4. Drill holes 3mm into the planets and sun pieces. Use M3 threaded rods and nylock nuts for secure connections. Attach planet 1 to layer 2 with three screws, making sure it turns smoothly. Secure planet 4 to layer 3 with equal ease. Assemble layer 1 over planet 1. Place layer 4 over the planets. Insert the sun stem into place. Add the top pieces of the sun. Next, glue the sun pieces to the sun stem for a strong bond. Use M3 rods for extra support and stability. When you've completed this puzzle, give it a good lubrication with vaseline to keep all the moving parts running smoothly. Finally, add some color to bring your creation to life!
