My sister in law inspired this creation by asking me to print her out a reusable gingerbread house. The one she wanted didn't stay together because the joints were a little loose, so I used my woodworking background to make sliding dovetail joints to help hold the house together. The model can be scaled down a bit but I wouldn't suggest going any lower than 75% because at 50% the rails tend to snap off.

Trying to organize my woodshop a little better so I came up with this design. I can already think of modifications you could make to it (taller storage areas for pencils and the like) so feel free to use it and modify as needed.
