I plan on making a box organizer for my utilities. I measured and 3D modeled these 3 first for testing and I got 1 out of 3 correct as you can see in the picture above.

I modeled the extra blades first. I took a picture of the container and I inserted them in Shapr3D (Ipad). So I measured everything correctly with a caliper. I did the same with my box cutter but I had to estimate measurements for some parts of it. Then for my scissors, since it has a different shape compared to normal scissors, I really took my time with it. As I finished modeling, I sent it to the printer (Bambu Lab A1; in case you wanna know) and it started.

I waited patiently and before you know it it was done. But what I got wasn’t what I was expecting. The box cutter didn’t fit, the blade container barely fits (too tight, no excess space), and the scissors surprisingly fitted the way I wanted it to.

TL;DR: I 3D modeled an organizer for my utilities but 2 of 3 didn’t fit so I’m asking advice on how to measure stuff properly and accurately.
