Box Stack Container - Peek-able

Don't listen to my partner... I DO like organizing things. Just... things that have to do with 3D Printing.These boxes are easy to print and will not only allow me to stack containers with projects, but also offer a peek inside when stacked so you can quickly find what you need, something I didn't find on the other boxes out there.This design is very inspired from Creative Tools stacking boxes here:https://www.thingiverse.com/thing:691127 How I Designed ThisWant to design your own stackable box
