Version 2 is available here. It is stronger and stacks even better.

This box is designed to be printed in vase mode for high speed printing. It is 125mm x 125mm wide and 70mm high. I used my Bambu Lab P1S with a 0.6mm nozzle. The grooves on the box add stability and there is a flat area under the handle for attaching labels.

Looking for a bigger box? There is a version of this design that is twice as long. You can find it here.
