These Milk crates are stackable and stylish. Each of these milk crates have a square on the bottom that has been specially designed to be able to fit nicely together with the other milk crates. The milk crates have been designed to be able to fit in with the gridfinity system with a 1x1x5 size. In order to fit with the gridfinity system you will need to print the gridfinity base which nicely fits together with the milk crate and can still fit in the top of the milk crate.
The print will need some supports around the bottom to ensure it prints properly. I am trying to work on a version that has the gridfinity base attached i just haven't had the time to finish it yet.
The milk crate has 3 different designs to choose from
