3D printers are seen by many as a novelty but this is proof they can create complex mechanical items that could be leveraged for many builds and tasks. The uses are endless!

See upgraded version of this gearbox with 3 planets at https://www.youtube.com/watch?v=n9uHey8INAQ
It was time to move away from printing solid objects and try to print moving objects. In this video I scale up a planetary gear set (transmission) that I picked up from thingiverse.com and I scaled it up to 200% to make it larger for a better demonstration. The end result after printing for 15 hours and a little cleanup is a functional hand crankable (or drill crankable) planetary gearbox. I can expand this gearbox to include as many series of planets as I want to reduce the gearing even more.
Let me know if you guys enjoy the video and I will create more gear sets and do a follow-up on this! Also the video contains a cool trick I learned for easily detaching prints from the build surface which can be a complete pain so watch the whole thing!
