Designed this box to store small items, customizable to different sizes for big and small printers. You can modify the box size, clearances, height, rows and columns. Just paste into Copilot or ChatGPT and ask for additional modifications. 
Please note that the shared models are flush but have a wide gap to be able to quickly remove the top. If you want a snug fit reduce clearances to 0 but add a lip or something, otherwise you won't be able to open the box (ask me how I know).
3 STL attached with 2x2, 3x3 and 4x4 grid sizes.
