Full credits for this orrery go to MatthewS3, who designed the orrery on which we (FabLab Zwolle, the Netherlands) based our one.
Our orrery works basicly the same as the orrery from MatthewS3, for the building details look at his instructable. (here)
All the wooden parts of our orrery are made with a laser cutter. If you don't mind changing the cutting plans it is also possible to make them with a milling machine.
We used the following materials to build our orrery:
Plywood 8mm, 3mm and 0.8mm
Brass tubes 2 to 9mm in diameter, all 0.4mm thick
Some plastic washers
