Brickfinity Fancy Boxes

Inspired by the various organization systems of Zack Freedman and Alexandre Chappel, I was never satisfied. All system do not fit in my drawers or boxes. 
After some back and forth I decided to create a system that is compatible with Lego. This allows me to use the space optimally and quickly create large buildings for PowerTools. 
Compatible bricks are available from various manufacturers at good prices.

The files attached are WIP and I look forward to feedback!

Filename is AxBxH where A and B are high and wide, H is the one in the grid system. A "normal" stone has normally 3H.

This boxes are “fancy” ones. This means stacking on top, oundings inside, smaller size but with more functions.
