Thingiverse citizen madscifi has designed what is sure to be a classic printable toy – a dump truck.  This one piece print features captive wheels inspired by a toy tanker truck by jag and sports a moveable truck bed.  While a one-piece printable, rolling dump truck with a movable bed is pretty sweet – what really wows me is the photograph of the interim design stages. Madscifi has been kind enough to share his OpenSCAD design files so that everyone else can benefit from his work too!

Okay, who’s up for designing a one-print, captive-wheels, working-hinges transformer?
