While I found some gridfinity drawers, none would be completely to my liking.

My criteria were

• Sturdy to hold screws and nuts
• Stackable for easy extension
• Use as little filament as possible for faster prints and less costs

The drawers do have a gridfinity baseplate integrated and no addition bottom plate. The grid is slightly extended, so bins don't hang through. There are no full shelves under the drawers, just some guide “rails” on the sides so save on filament. The guides have a small bump in the front, so drawers will stop before falling out.

The cases can be stacked and secured using M3 countersunk screws. Same type of screws can be used for the knobs, combined with hwatever you like. I used M3 hammer-nuts, as I have to many of those around. You can also make custom knobs using threaded inserts.
