Expandable Dovetail Container System

I needed small containers and because I dont know how much content I'm going to accumulate it must be expandable.
So I designed this dovetailed container. You can store everythink that fits in it with them. I use them for medicine bottles but the possibilitys are as endless as the expandability!

The ones in the photos are printed in 100% size(2.5cm x 2.5cm x 3cm) with 20% filling and layer height of 0.15mm(red) and 0.25(green).

I'm going to design bigger ones with the same dovetail joints soon...

UPDATE: I recently added a 1 by 2 version to the files
