Pocket-sized icosahedron

I’m large and in charge.

1/8" BB plywood. 19" or so edges. Could go a bit bigger if you wanted by using the diagonals but I just wanted to crank it out to say I did it :wink:

Banana for scale…

This is dumb.

Cool! But that’d be one large pocket… :wink:

LOL if you did this model in the same method:

… it’d be about 15 and a half feet across. This is just silly.

NOW you’re talking!

I gotta say though, I’m betting the construction is far less fiddly when your bars are 19" across :stuck_out_tongue:

Yeah, but it had its downsides too. At that scale 1/8" ply flexes a lot, especially if your pieces run across the grain. The whole thing wasn’t terribly strong until it was complete, I was worried I was going to crack a joint right up until the last piece was fitted, and then it was self-reinforced and fairly sturdy.

Can you paint it and hang it from a tree? :slight_smile:

If each pentagon was solid and you had a “H” type extrusion to put the pieces together you would have a dynamite dome with many possible Architectural uses.

I think you need to add some fabric and make an icosahedrontumbleweed.
