Sun & 4 Planets

The idea for this gearset came from the following posting I saw online:

Since I use Grasshopper to make all my designs I thought I could use this method to make a small gearset that would be a nice demonstration of the Planthopper software add-on to Grasshopper. So I installed it and started working.

Well, it turned out it was more complicated than I expected. Planthopper was made to produce precisely machined metal gears. It does not account for the dimensional inaccuracies inherent with all 3D printers and their printed results. So I had to make several adjustments to get a good result. Plus I had to add a handle to one of the gears to make the whole assembly easily workable. The STL files included here are the final result.

Here's how to get everything working OK:

1. Print the base. This is a simple print that holds the gears in the proper orientation.

2. Print child.stl. This will produce just the 4 child/planet gears. They will
