3 boxes

3 boxes with the same size, but they all open in a different way.
this was mainly a practice in opening mechanisms.

the boxes are named- first/second/third box, 'shell' is the box itself and the rest are the openable drawers. the 'unit' assembly parts show the finished boxes.

the first box needs only 1 drawer, the second one has room for 2 drawers, and the third one needs 4 drawers.
