On September 24th, we celebrated our 10th anniversary as a company. Our first sales event was a little parking lot event at a Maker Space -- we sold planetary gear pins and 3-D printed gears. Soon after that, we invented a planetary gear coaster. That first coaster featured a propeller and it was available for sale at SteamStock 2012. In the years since then, we have modified that first coaster many times and added lots of options, including coasters with elliptical gears, nautilus gears, and layers.
