We use quite a lot of spray paint in my job, and I designed this holder to fit inside our toolboxes to keep the cans secure and organized. It’s modular, so you can connect as many as you need, and it holds up well with 15% infill (just make sure to print the pins at 100% for strength). If anyone wants different layouts—like 1×2, 2×2, or other combinations—drop a comment and I’ll make them up.
