Hi folks,

Been ages since I posted here, but I finally put in the effort to complete my shallow-cut Dino cube, made from paper, which I think I started over 3 years ago! It's not that it took that long, just that pieces weren't lining up well and I shelved it. Has anyone made this puzzle before?

You can see my page about it here: http://www.software3d.com/ShallowDino.php

Nice one!

As I had stated before, Dino Cubes can be so much more attractive when they have centers!

Now here is a case where someone really knows how to fold paper into a square. :) Very cool visual art, Robert.

It has taken more than six years for this to become real:

Really cool and well done.

That is one beautiful piece of artwork. My mind boggles at the skill needed to make this!

Ooh, looks very cool, and I'm amazed you made it out of paper :) What exactly makes this significantly harder than the paper Dino Cube you made? Was it the difficulty of getting the pieces to line up?

This was going to my next trip into CAD. I think I'll still do it eventually, but I want to get something done that no-one else has done yet.

Haha, as soon as I saw this topic I thought the same thing :lol:

One thing with paper puzzles that I have always wondered is how is the stability?

I've thought of making that 2 days ago :o

Good work on that one! :)
This is made from paper you say? Nice!
Are you planning of building one in casting/CADing?


Cheers
Nikola :)

I don't think anyone has made that before. But it is a pretty trivial puzzle both solution and mechanism wise. But making it from paper is a great feat!

Somewhat related: A very nice application is Pepakura. It can read STL file and can fold them out to make a pattern you can print out, cut and then fold into the pieces. Might be a good idea for someone who wants to do something similar. It doesn't really like fillets but if you avoid those it works quite well. Except for the scale, that is.

Thanks for the feedback guys. The reason I made it out of paper was simply that paper is my medium and it seems I have no skills with plastic or any other more sensible medium. I briefly tried my hand at casting, but it didn't turn out too well, and I found that I couldn't even manage to sand paper a surface flat! It just kept ending up pillowed, even when I kept the sand paper flat and moved the piece along it carefully. I probably just gave up too early. Pity, as there's a bunch of interesting and novel mods I'd like to create. What I need is someone to run a workshop! :D

I used thicker paper, thinking it would make stronger pieces, but the thickness of the paper itself accumulates as error in the measurements, so yes, things didn't line up well. In fact, I had to cut a section out of the arms to the vertices to shorten them. You can see it in my photo. There's also just more pieces required, and some other things I did in an attempt to improve the robustness of the puzzle that really just backfired.

Pretty bad! My first one operates a bit better than this one I think. Here there are tracks cut out of the vertex pieces, but there are also tracks under the face pieces, and the two different types of tracks don't seem to line up perfectly, so the edge pieces have trouble finding their way without help.

I guess it's more a proof of concept than a usable puzzle. Of course, it may well be possible to make a much more stable puzzle from paper than I have in my attempts. I'd love to find a way to make it really robust.

No, I'll leave that to those with more skill in that area :)

I agree it's pretty trivial conceptually. Unfortunately making anything from paper limits the complexity of what's doable.

What do you mean by fillets?

I believe he is referring to the rounded edges that many puzzles have on individual pieces.

I must say that building a functional puzzle from paper is quite amazing, and I am saying this an both an amateur puzzle builder, and an intermediate origamist. I have to ask: any chance of seeing at least a crease pattern or cut template for this feat of functional paper craft?

Maybe if you don't mind would you mind giving the nets of the pieces out? like attach them to a post or somthing

I would very much like to build one of these they seem very cool


Good Job =D

Thanks. The nets were mostly small, eg about 4 connected parts max. If one was to make another one, I'd suggest rethinking it for a better result. I printed the nets directly out of Great Stella (software I wrote, for the sake of full disclosure :wink:), so I'm afraid I don't have them in PDF format or anything.

I suppose I should comment here seeing I was working on it back then, and again last year before dumping it for my current project.

This is a tricky puzzle. I thought my design was actually working a few weeks ago and then discovered that the edge pieces come too far to the surface and would pop the centre caps off. So it needs more work.

The paper one would get away with this because the internals can flex nicely, and thickness is less of an issue.

I'm not interested in pursuing this anymore. Would you guys like me to post images and .blend (blender 3d) files of the design so that anyone can pick it up and keep going with it?
