Hello,

I would like to present my new puzzle - Little Chop / 24 Cube with magnets.
Due to mechanical implementation is too complex, therefore I decided to create
Little Chop Cube with magnets. 3D model of the cube for shapeways was created
by Evgeniy Grigoriev (aka grigr), assistance with shipment to Saint-Petersburg
by Alexey Gurov (aka Tesseract750).

Enjoy!

Video: Little Chop
Related topic: Makarov's / Mixup / Hedgehog Cube (magnets)
Buy at: Shapeways Shop

Best regards,
Vladimir Yaroslavskiy

EDIT ------------------------------------------------------------------------------------------------

You need 40 mm sphere and
(3+3) * 24 = 144 magnets with 6 x 2 mm size (diameter x width).

ADDON ---------------------------------------------------------------------------------------------

Magnets you can find on ebay
or if you are from Russia, you can order it on http://www.pmspb.ru.

In few days I will put tutorial how to make metal sphere by hand, please, wait.
New pictures of the cube with stickers will be posted very soon.

This is cool. As far as the shapeways product is concerned: I suppose shapeways doesn't make it with magnets and the sphere inside right? :D
So what is the size of the sphere and what magnets did you use?

I have updated the description of the cube:

You need 40 mm sphere and
(3+3) * 24 = 144 magnets with 6 x 2 mm size (diameter x width).

Wait. Why is the black one on shapeways cheaper than the white one? Isn't it normally the other way around?

Shapeways has recently introduced a feature that allows you to have different markups for each material. I think Grigr set a markup for the white version, but forgot to set one for black and other materials.

Awesome! I really like Little Chops. I won't be buying this however, as some people know I'm terrible with magnets! :lol: It still looks pretty cool.

Very interesting!

Also, seeing the picture of the internal sphere and knowing that it's 40mm in diameter, I believe it's a ping-pong ball. I had this idea of using it in a puzzle before, so I know how it would look. 8-)

Wait, so if this uses magnets, could you do a dino turn also?

Very nice, the turning seems worse than your magnetic Mix-up cube, is there any reason why these puzzles that use the same "mech" turn so differently?

You would have to pull the pieces apart for a dino turn, as the cutting planes are different. See the first picture, the cuts do not line up for a dino turn.

Aleksey, you are right! It is standard 40 mm ping-pong ball. I will put video with details very soon.

Mixup cube has more stable construction and therefore it's easy to turn. No parts of Mixup cube interact by magnets whereas parts of 24 cube do it.

Wow! This is exactly the idea I had for the ping-pong ball long time ago!
Your way is cruder are easier for everyone. The differences with my idea are:
- I used metal powder.
- I filled the ball with oil and sealed it.
