I discovered a nifty tool called Pepakura. It can turn 3D models into paper models! To test it out I turned one of my (previously unseen except by Draco) models, a sign for the Jungle River Cruise (which goes in one of the late JPO levels, level 4 I believe).
I plugged it into Pepakura, printed it onto cardstock, cut it out and glued it together:
I can see lots of papercraft InGen crates and toolsheds being made! Note: The more pieces, the more complex your model will be. Plus, being Japanese, the tool uses millimeters/centimeters instead of inches. You can set the assembled height to any height you want it to be. Plus it also automatically imports the textures and UVW mapping. I recommend only using low poly models (like.. under a 1000) because of how complex it will get.

Imagine making a to-scale East Dock sign for a toy diorama :O
