About this 3D model
If anyone wants this in something other than plastic, I uploaded it to Shapeways. http://www.shapeways.com/model/949238/tardis-stash-box.html Its bigger on the inside. The 2nd and 3rd file are the top and bottom split. The 4th file is the top altered to fit the bottom better after printing. I made the groves larger by about .5mm
