I do a lot of free-standing "holders" from industrial (5 ply) cardboard and hot glue. Surprisingly sturdy! Made a video about this too: https://youtu.be/s-aNW3h15K0 - all of these are still in use and I made more & more complex ones too.

Seems the calculator is designed for a "collection of boxes", which I guess is a start, but when I hear "organizer" a collection of separate boxes ain't what I want. The most significant factor of making one's own is that it's 105% customized to the need, no more no less. That means usually a lot of thought between "target place bounding box" vs "bounding boxes of things the holder shall hold".

For "organize a drawer, quickly!" I got myself a couple of sets of "modular" boxes - they have little tabs on their sides so one can snap them together like lego.

Your cardboard holders look cool, I'll give this a go. Thank you for sharing

Pro-tip I only realized later when making much bigger ones: it's worth to pay attention to the "grain", that is the orientation of the corrugations.

Find it hard to describe, but they should go "perpendicular to the axis of load". E.g. if you have an upright wall the top and bottom edge should show the "waves"; your base (and top) plate should have the "waves" showing on the left and right edges.

Took me some time to get used to thinking about it and it makes cutting out individual pieces (a lot) more involved, but the payoff is real for big units (big as in 50 x 30 x 40 cm; no longer can you move it one-handed!).

That is a very cool idea. I have been struck in the past by the sturdiness of certain “heavy duty” cardboard boxes, but it never occurred to me that it was so obviously a material with DIY potential. Thank you!!
