I'm so glad I made this investment. It reminds me of how "game changing" the first home PC's were in the early 80's.
We just got our MakerBot Replicator last week, and the whole family is excited to get making things!
We plan to share:
Most of this will likely be simple designs, that my kids can build, as they gradually learn CAD & the Makerbot. If/when we get "great" designs going, I'll also upload them to Thingiverse.com, where there's a great & growing catalog of printable designs from a great community of engineers around the world.
