Hi Twisty Puzzle fans,

Slice Kilominx is an idea by Bram Cohen, designed, developed and prototyped by me.
Watch the YouTube clip
Buy at Shapeways
Check out the photos below.

As you may know, there exist several versions of Kilominx, including

Bram Cohen came up with the idea of the Slice Kilominx. His idea is that all opposite faces turn as if they were connected. Bram explained to me in detail how to design this puzzle, using the Jaap's Sphere tool by Jaap Scherphuis. With the coordinates by Bram on Jaap's Sphere, I could make a shells-type design and I built the puzzle. The puzzle turns rather stiff. I think this is caused by the roughness of the nylon SLS 3D print in combination with intrinsic properties of this design. After a lot of turning, it got quite a bit looser. It is a fully functional puzzle, which is very confusing and hence quite hard to solve.

Enjoy!

Oskar

Mr Van Deventer, you are an icon among these forums and you and Mr Cohen seem to defy the laws of science and mathematics with your puzzles. This is another example of exactly that. This is fantastic!
Reminds me of your Geary cube, but more stiff :lol:

Very well done to both of you.

That thing does look hard to turn but it's still a great puzzle! Well done! :D

Like the geary cube, only they both turn the same way and without gears!

I have always wondered if you lube your puzzles? Do you add in extra tollerence in the design for the sls? Do you do anything to the printed pieces before you stick them into the puzzle? Thanks, Tanner.

Hey Oskar great puzzle!

Also in your signature I see the hollow cube printed. Going to make a video of that one soon? I really want to see how that one looks

Wecome Oskar, great first post which I hope is just the beginning of many more. My favorite part of the video was this part...

Quote:
Bram explained to me how to design it. He showed me with a with a tool that's called Japps sphere how to make the deep cuts...


I too wanted to call that a deep cut but I doubt that is what Bram called it.

And let me second the request for a video of the hollow cube. The 7th one over in the back row...

I have not had the pleasure of playing with one of these (though Oskar had many other great designs at IPP), but I will say that I quite enjoyed staring at the mechanism on the Shapeways page until I could grok how it worked.

Edit -- oh, the mechanism shot has been removed? Too bad!

Yay, Oskar's here! :D

I love the concept for this one, personally. It's interesting to note that opposite pairs of pieces will always stay the same in relation to each other, so all you have to worry about in the long run is one of every pair.

This makes me wonder... is an actual Geary Minx possible? I'm guessing not in the same way...
