Recently I bought some sorting boxes on Amazon from a seller which could be bound together. I found the idea realy nice and you could stack the boxes very easily.

• Boxes on Amazon

I decided to buy them again and this time the same boxes were delivered with only one difference the connectors were missing. I contacted the seller but he was not helpful at all so I deciced to design my own connectors and here they are.

Maybe someone will find them helpful.

I printed them using eSun ASA+.
