Summary

So very meta. A tiny 3D printer you can print. Like reprap, but smaller.

Instructions

You may need supports to print, depending on the orientation you print the parts.

Print printsurface.stl in natural PLA
Print cart.stl in white
Print the other parts in whatever color you'd like the Cube to be
Glue cart and gantry to base (do cart first, it will give you a better glue surface to use for gantry).
Glue zaxis.stl to the gantry
glue the print surface to the zaxis.
If you have a tiny part somewhere, you can glue that to the print surface to simulate a little complete print (see my photos).
(optional) glue a little but of cable between the hole in the gantry and the head to simulate the filament.
