In a previous post, we mentioned some developments using a gear generator with Grasshopper. We’re looking forward to applying the tool for practical applications, but for now here’s something completely impractical: a gear cube version of the Seattle Central Library. This was a project of ours in collaboration with OMA back in 2004 and is just a couple blocks from our office. We’ve decided to turn the project on its head.
Using the gear generator, this was a simple setup using these steps:
This setup draws from Emmett Lalish’s cube gear design as posted on Thingiverse. The original cube has gotten a great deal of attention in the maker community and is a lot of fun to play with and figure out. We’ve posted the Library model on Thingiverse as well. Also, at the bottom of the post you can download a very basic version of the gear generator for Grasshopper (two-dimensional gears at the moment, work in progress). Enjoy, and please share any results!
