Hi, this modular organizer is made for small items like nuts and screws, electronic parts,etc. You can do as much modules as you want. Modules can be put together on all sides, top/bottom, left/right. Modules are made for 4 and for 2 drawers. Designed for relative small 3d printers with 220x220 table.I made them on ender3v2, and i made them out from recicled pet bottles-diy filament. i assume pla will work better.Sizes in mm:Modules 205.2x45.2x70 (LxWxH) Large drawer 96x74.4x38-with handleSmall drawer 48x74.4x38-with handleThanks!
