Dude! Why are you here? You should be looking at my awesome new tiny C64 - http://www.thingiverse.com/thing:150957
I wanted a shape to wexperiment with gluing and painting, so I created this mini C-64. Four pieces, should be obvious how to put them together.
Glue the two halves of the top together, then insert and glue the keyboard, then glue it all up with the bottom piece.
I used cyanoacrylate (superglue), and the body was printed on Zen Toolworks white PLA, sprayed with Rustoleum "Fossil" paint (satin finish).
