Burr Anonymous
This is a picture of a Burr Puzzle I have started to make by origami.

I ran into some structural problems; the pieces are very fragile. I am thinking doubling the size might fix this problem.
Any other suggestions?

heavier paper maybe?

Use thicker paper. Using larger paper of the same thickness effectively is like using thinner paper, which would basically make it more fragile. Also, rather than having all those exposed edges, if possible (as in Jeannine Moseley's business card cubes for the Menger Sponge) using additional pieces, cover the outside so that each cube face has only a single panel. This will make it better looking (it's cleaner) and more sturdy, since you will have an extra layer.

Yeah, if you glance towards the bottom of the shape you will see this piece is already partly faceted.

But the difficulty appears to be paper thickness.
I really like the idea of building a complex model just from a pack of sticky notes, so I'm going to tinker with construction a bit and see what I can do to shore up these structure weaknesses.

Thanks for the feedback.

I've made a lot of burr-type puzzles from wood, so I have some thoughts.

1) to make a burr work decently, the cubes have to be perfect in their size and the flatness of each face.

2) Even if I made perfect wood cubes, I generally had to sand them after I glued them together to keep edges from catching.

Like>>59532,
I'd think of doing it as makint all the cubes, then cut out a profile of the piece after gluing the cubes and glue it on as a facing for each face that was more than one cube.

Even then you'd have to be very careful if you were using it as an actual puzzle.

You could also make it out of "paper before the lignin is removed" :)
