Inside boxes: https://makerworld.com/en/models/56160#profileId-57760
My new and favorite box so far with smaller boxes inside to very easely pour out all of the content or move it.
This is the medium version and comes in 2 size variants and each with 3 height variants.
Works great for screws or accessories. You can change the layout whenever you want, just print different sized inside boxes! :)
OBS! These larger lids can warp a littlebit and may cause them to catch the inside boxes but this can be fixed by just bending the lid a littlebit to counteract the warping. :)
The inside box slots are 30mm squared
