Modular drawer cabinet

UPDATE!!!The 3D printable, replaceable label drawer version is now available:https://makerworld.com/hu/models/2299983-v2-drawer-for-hobbybox#profileId-2510098 ----------------------------The drawers of my existing, store-bought parts storage unit were worn out and broken. First, I designed inexpensive printable drawers to replace them, with dimensions compatible with the popular "Hobby Box" storage system in Hungary (35x54x140mm).https://dobozrendelo.hu/spl/104329/Hobbi-Boxhttps://www.zenitkft.hu/Hobby-boxok-tarolodoboz However, in a hobby workshop there is never enough space to store small parts, so I later designed a cabinet with it, which allows me to expand the capacity with a uniform look and unlimitedly. During the design, I also kept in mind the economical use of materials, structural strength, comfortable use and easy printing. Therefore, it is cheaper to print it than to buy it ready-made. Based on the testing, it can withstand even if I pack it full of metal screws. P
