Micro Digger

Description:
As I have now a Micro Dumper ( http://www.thingiverse.com/thing:32773 ) I need something to play with. And what matches a Dumper? Right - an excavator.
My Micro Digger is 25 x 25 x 23 mm (1 x 1 x 0.9 in) and has a fully working arm. It comes with two shovels. One is a standard shovel and the other one can be opened.


EDIT
I never liked those axis pins. They are always to loose or it is too hard to push them in. So I design new pins with a flexible clamping zone ("flex pins.
