This is a from the scratch adaptation of dhiltonp's excellent gridfinity storage box, to fit with Alexandre Chapelle's ALCH storage system that I am using a lot throughout my workshop and office.
The box has one 23mm, two 20mm, two 11.4mm and two 9mm storage tubes. In addition in the center two inserts for smaller cells, in stage I have only 6.5mm diameter cells in use.
The box looks like a piece of Swiss cheese, but does well its storing job.
