I spent a long time looking for a way to organize my countless small parts. At first, I went with the incredibly high-quality T-BOXX 320 from Sortimo, but unfortunately, they’re insanely expensive. Even after getting my eighth Sortimo case, the chaos in my apartment didn’t get any better, so I decided to switch to Euroboxes.

But how do you keep Euroboxes organized? I started looking for insert boxes and found plenty of options. Most systems required shelves, which wasted a lot of space, or they left gaps around the edges where small parts would constantly fall through.

So, I decided to develop my own solution. Due to the inner rim defined by the Eurobox standard, a slight taper towards the bottom is unavoidable. This actually solves both of the issues mentioned above and creates a clean, uniform look. Unfortunately, because of the interior dimensions, it’s mathematically impossible to design the insert boxes in a way that allows them to fit in any rotation. That’s why I marked the front-facing side with a triangle. I’ve visualized all these details in pictures to make them easier to understand.

I hope this is useful to you! It took me a ton of trial and error to come up with a version that I was truly happy with.

Stay organized to keep your focus on what really matters! 🚀
