A kind of puzzle that builds a sphere with 4 different pieces

it's just for fun and because i like spheres

I cut this with openoffice/draw ( http://download.openoffice.org ) on a zing laser cutter ( http://www.epiloglaser.com/zing_laser.htm )

This is to cut in 3mm thick, for example MDF

cut until you got
24 wheels with 5 slots
40 wheels with 6 slots
60 curved with 2 circles
30 curved with 3 circles
... and some spares

insert 5 "2 circle curved" pieces between two "5 slot's wheels"
once you get 2 of these, join them with the "6 slot wheels" and a "3 circle curved"

continue, you'll get the sphere

And many thanks to http://www.thingiverse.com/souriceaux06 for his conversion of the thing to ".dxf" format

thanks to http://www.thingiverse.com/amk for the plans of his derivative of 4mm with legs

Ok... english is not my main language... i do my best
