This orrery shows the revolution of the six first planets of the Solar system : Mercury, Venus, the Earth, Mars, Jupiter and Saturn. There are 18 gears driven by a crank.
You need an empty Prusament Spool to build it. If you don't have a Prusament spool, you can print one (use "Spool_Prusament_NFC" in "All Individual Parts")
This planetarium is adapted to the new Prusament Spool NFC and also to the "Classic" Prusament Spool. Choose your files according to your type of spool.

Edit 2026/05/20 : new file "Spooletarium_Classic_Structure_Edit". There was a mistake in this plate. It was noticed by @BrianAmato_717081 (thank you so much !). If you had already printed the old file, you need to print a "Support_(Classic_Spool)" (see in "Individual Parts").
Edit 2026/05/01 : new ring to increase pillar stability
Instructions :
Structure :
Gears :
Crank
Pillars :
For more stability you can glue the rings to the spools.
Planets : glue the planets on the supports
Planets Revolution :
The following multiplications indicate the gear train used for each planet.
Earth : 365.256 days (reference)
Mercury : 365.256 x 13 / 54 = 89.932 days (real : 89.969 days)
Venus : 365.256 x 24 / 39 = 224.772 days (real : 224.699 days)
Mars : 365.256 x 47 /25 = 686.681 days (real : 686.979 days)
Jupiter : 365.256 x 60 / 12 x 64 / 27 =4328.96 days (real : 4332.59 days)
Saturn : 365.256 x 60 / 12 x 53 / 9 = 10 754.76 days (real : 10 759.23 days)
