Stackable screw tray

I know there might be doubts given the high quality of the design and photographs, but no AI was used in this product.

Jokes aside, it is something designed to meet a real need. Like many 3D printing enthusiasts, I like to make my life complicated, so I decided to build a 350mm 2.4. Everything is fun until you get to the bag of screws—that's when you realize the problem you've gotten yourself into. A smart person would use Gridfinity, but not me; I prefer to make things complicated and design my own stackable tray system.

As you can see, there are several types of trays: from a 5x5 grid designed for storing screws, nuts, springs, SMD components, etc., to a completely open one for bulk storage of larger parts. There's another 5x5 version with a slot for tweezers, and one with four large compartments meant for an electric screwdriver and its bits. The basic idea is to make working in your workshop convenient without taking up too much space—plus, the fact that they're stackable makes things a lot easier.

I could give you a spiel about design philosophy, the golden ratio, and all that other stuff that makes a product sound more "marketable," but I really can't be bothered to fire up Claude or GPT just to generate some fancy, pretentious description for what are—let's be honest—just stackable boxes. At first, it was nothing more than a tray with a 5x5 grid of slots, but little by little it has evolved into this. Honestly, I'm very happy with the result. I just hope you like it and find it as useful as I do.

The profiles I uploaded use 3 walls, 10% infill, and supports, since the overhang is at 90°. However, it is possible—and I have done so—to print without supports if the finish isn't a concern for you. You could also lower the infill to 7–8% without too many issues.
