Portable Modular Storage Box

I came up with this as I was looking for a way to transport small electrical parts in a backpack with them getting all mixed together. I wanted to make something durable, customizable, and most importantly easy to use. After several iterations and lots of filament wasted, here we are!

There are two box sizes, both have a dovetail lid which slides in from the side and is held in place with a simple spring loaded latch. There is a button on the side which lets you release the latch, simply by pressing it down. There are several “bins” you can print for them, all different sizes depending on how you would like your box setup. The final feature I added was dovetail on the bottom of each box so you can slide the boxes on top of each other. 

Printing Instructions

There are no supports needed besides some for the button. I recommend printing this with 2-3 walls and 20%-30% infill. I printed most of my boxes in PETG for added strength but any material will work. 

Assembly

The only assembly required is of the latch and button. You will need a spring, I use the springs from ballpoint pens. Put the spring in the groove on the latch and put it into the box where the latch hole is on top (make sure the flat side is facing towards the opening). Then while pushing it down into the hole, insert the button through the side and twist. I designed to be quite snug so it might take some fiddling. 

Feedback

If you have any feedback on this design please leave me a message and I will do my best to respond quickly and see how I can help. I will continue to improve and add more to this project as time goes on. Suggestions are welcome!
