Slip fit Strong Case Free 3D print model

I received my 3D printer a few months ago and this was the first design I created. I was looking around at things to design in a few minutes and this happened - I have these stinky Artist pencils that needed a sealed container.

The intent of the design was to create something strong, light and helped me understand Shrink and Slip-fits with 3D Printing. It's completely over designed and might take a drive-over with a car.

Anyway - it will fit Pencils, Jig saw blades, nails, anything flat and long that needs protecting.

I can't guarantee that the slip-fit will grab with all materials - some shrink more/less than others.
