Really? That would be so cool xD

I mostly did it because my other one was so expensive ..
Had a lot of fun figuring out to make a design where all parts fit in whatever rotation you choose.
This base is basivally a Rubik's cube without colors ^^

Also:
I plan to add two more pieces, a side cover and an alternative edge.
With a side cover for the corners one can build only parts of the ball and with the alternative edge one can elongate it.

Not really sure if I want to make a cross section or an inner edge, though :D

Nice work! I think you are the first to make a modular asteroid mine.
