Box holders

I created box holder / rails from standard 3l box from pepco (label of box attached at image)There are 2 option of holders:One sided, used for one boxDouble sided for connect 2 boxes near.You can also use combination 1x double sided + 2x one sided for connect 2 boxes near.You can attach box from below the table or shelf as is visible on images.Holder are for box without lid. If you request, i can prepare stl file for boxe with lid.
