Modular Screw Box

I got to talking with a friend and saw a few variations of these around youtube and decided to try and design my own. This is my first attempt at designing something to be printed from scratch and I thought why not something simple.

This is a modular box that can be changed to any rectangular formation. You then attach the screw caps to each wall and wallah you have a box.

Future goals for this is to add a top that can be hinged and or closable.

*** UPDATE ***

So made the walls and base a little bit thinner. Watched some more videos on fusion 360 and made the screws easier to screw and even was able to remove the need for enlarger the cap.
