This is a makerbot-sized interlocking 2V/L2 icosahedron dome (reference: http://simplydifferently.org/Geodesic_Dome_Notes ). Might be useful if you're planning a moon colony or are building a really small radar set. Or print it in PLA and you have the shade for a nifty lamp. In any case, here it is.

Notes:

1. You'll need 30 of the A-A-B panels, 10 of the B-B-B panels, and 10 of the B-H panels.
2. This should be about 30cm in diameter and about 20cm high when assembled.
3. The panels should be error-proof, i.e. they should interlock only one way.

UPDATE: I have added DXFs for anyone who wants to use a lasercutter.

1. Print all the panels (or lasercut them)
2. Assemble (with glue if necessary)
3. Hand over to your pet hamster, put atop a tiny radar, or whatever suits your fancy.
