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

Looking for a shorter box? The square version of this design can be found here.

This box is designed to be printed in vase mode for fast printing speeds. It ist 125mm x 250mm wide and 70mm tall. I used my Bambu Lab P1S with a 0.6mm nozzle. The grooves of the box add stability and below the handle you have a flat spot for putting on labels.
