Pyrhombic Crystal (Pyraminx shape mod) *video added*

Justin · **Posted:** Wed Oct 15, 2008 6:32 pm

I actually made this from a Tetraminx rather than a Pyraminx. I've never made anything this small before and made quite a few mistakes en route, which fortunately I resolved.

The spring/bearing system which makes up the "click" mechanism had to go - no room.

Somehow I managed to shoehorn in an extremely shortened spring and a washer into each main screw recess (which had to be drilled to make the room), so movement is surprisingly okay.

I made an interesting discovery about the volume of the pieces: the 6 rhombic dodecahedron edges pack perfectly into the shape and volume of the Tetraminx edge. The 4 corner pieces of the rhombic dodecahedron pack perfectly into the same shape and volume as the Tetraminx corner piece. I've included a photo down the list to show this.

It's a trap!

Nice build. I like it. Can we get a video?

As soon as I saw your new avatar, I knew it was going to be amazing. And it is.
Very original idea. The stickers look absolutely perfect too.

Err... to quote a Yorkshire phrase,

By 'ec, it's reet good!

How do you work so accurately with something so small?

great stuff.

So um, if I let myself get caught in the trap, can I have the puzzle?

Really cool!
It would have been hard to guess what this was made from if you hadn't mentioned it in the title.

I looks very tiny in the video.

That's so tiny...
...but so perfect! I love it!

I'd go completely nuts if I tried to build something that small!
