Re: [Origami] Albrecht Dürer polyhedron in Melencolia I

Hi,yes, I was just thinking that it looked like a cube with two opposite 
corners cut off. I believe they call this chopping off corners as a 
"truncation":  https://en.wikipedia.org/wiki/Truncation_(geometry)
The only model I know would be David Mitchell's Columbus cube. I have made 
something similar with business cards.  You can adjust the diagrams to truncate 
two corners instead of one.

Hi Laura,

>>I’d like to fold the polyhedron that appears in Melencolia I, the famous 
>>engraving by Albrecht Durer.
>>What would be the best match and where can I find the diagrams?
It looks like a cube truncated at opposite corners (and slightly 
squished!)
 I'm not aware of any diagrams that would match it exactly. But in the 
spirit of throwing open a challenge, would you be looking for edge units or 
flat face units? Edge units you'd 6 each of three different sizes. For flat 
face units you'd need 6 of one and 2 of another, but I suspect that it could be 
done with 6 identical units with a clever lock to make the other two faces 
(which would have creases).
I'll ponder it, but I hope that some other geometric or modular folders 
out there will give it a shot!
