Gotta love a good box. The snaplock design from Hugo is great, but I wanted custom sizes and a few printability improvements. Combining my previous Tough Box learning together, and remodeling this in Fusion, you can now make up any sized you want. You can also tweak the wall count, layer height, thickness, and more through parameters. Additionally, as you resize the box, more or less hinges will automatically materialize!
To assemble, I place the top cover on the box lining up the front and then forcing the hinges together. Snap the clasps into the top and they then lever down.
The author remixed this model.

Remodeled the rough concept, but incorporated much of my design learnings from the Parametric Tough Box. Interior is specifically designed to match the dimension parameters to it's easier to make inserts which don't need specific chamfers/edges/etc.
