I’d really like to see a robust printable open source interconnecting building block system for the MakerBot.  Something than can build large (or small and intricate) rigid structures with moving parts.  So far there’s:

1. The lazzor-cutable metabrick from metalabs.
2. Lego compatible laser cut blocks by clothbot
3. The printable metabrick by wizard23

Of the one printable variety, it doesn’t really lend itself to rigid structures as it uses a round clamp to attach to a round pole.  Don’t get me wrong, it is a very cool piece and I’m really glad someone designed it – it just isn’t what I’m looking for.

I’m wondering if a slot/groove system might work – similar to the system used in Zaggo’s prinstruder or the modular boxes by Domonoky.
