The file 'Tiny Toy Dump Truck With Cam Action Bed 3D Printer Model' is (scad,stl) file type, size is 17.7KB.
This is a variation of the Tiny Toy Dump Truck that does require support in order to print. The use of support allows cylindrical wheels, a bed axle sleeve that is no longer sliced, and the addition of a cam and rod that lifts the bed once per rotation of the back axle.
It can be printed as a single piece on a standard Reprap/Makerbot by manually introducing support material during the print.
