Orrery: A Model of the Planets


I 3D printed and built this great model of most of the solar system.

Here are the posts I have made so far about the Orrery:

Building an Orrery: Planets!

Now with the gear set assembled and turning nicely (I could hand-crank it by turning the central shaft from below the base), it’s time to add the main attraction of the planets.

Construction of the gears of the orrery required more than a little patience working with the printed parts and bearings.

Building an Orrery: Bending the Rods

While the parts were printing I got to work figuring out how to best bend the copper rods that attach the planets to the gears. Ytec 3D provides a printable guide to make sure each part was the right length and shape.

Building an Orrery: Printing the Parts

An Orrery is a mechanical model of the Solar System where the planets orbit around the Sun with a combination of gears allowing for relative motion between the sun and planets. I found a great tutorial on a 3D printed version that I could make as a present for my Dad.

The build guide comes from Ytec3d’s guide which links to the instructible he wrote, be sure to check it out and support this amazing maker.
