This is of course much simpler than Hidetoshi's Bump cube, but as it kinda looks the same, I named it the Simplified Bump Cube. In my mod I 'moved' one middle layer off center. In the original Bump Cube all three middle layers are off, creating 26 different pieces.

I took a Twisty Puzzler and cut away as much as possible of one of the centers, which is 7.5 mm. The original Bump Cube of course goes even deeper than this (my thinnest layer is 11.5 mm, the thinnest layer on the Bump Cube is 9 mm.). I think I figured out how this is done. And perhaps one day I'll have a go at it. Although that will be much more time consuming than this one.



I shortened the spring and used a smaller screw.



I used Apoxie Sculpt to fill the other pieces of this layer.



Let it dry and then saw and sand these pieces down to the level of the centerpiece. Keep the bits that you saw off.



'Simply' attach these bits to the other side. I used Apoxie Sculpt for this. Remember that the sawblade removed half a millimeter or so. So take good measurements. For the center piece I used a corner piece of another cube. Sand the pieces.



Paint.



Cut stickers and you're done.

Hmmm... this looks easy now. Why did it take me so long then?

Wow, awesome! i see your enjoying your new plotter

Excellent job Thomas..... I look to be making a bump cube when i finish my current project(Master Cuboctahedron)... So I will be in tough :p

Excellent mod! It really made my brain bump for a moment!




Pantazis

nice, I have to try that sometime (another project added to the super long
list of them).

It looks very well made. You make it look so easy

Would it be possible to do those same lengths of cubies only in two or maybe all three directions?

Two great puzzles in two days! this looks perfect!

Thomas, this is fantastic job!
Very well made!
You are now in "Masters of puzzlemaking" list!

By the way, how long did it take you to make it?

To each saint his candle! Congrats!

Very nicely done, Thomas!

That apoxie sculpt is it pretty easy to work with? Does it set up well?

I've been having trouble with the miliput.

That is soooo cool. I would like to buy one. How would you solve it? Just like a normal rubik's cube right?

Yes, but that would be much more time consuming.
I think then it would be best to make the pieces from scratch out of plastic card.
If you use different sizes for the three directions you get the Bump Cube (see http://www.asahi-net.or.jp/~wq6h-tkj/bb ... #BUMP_CUBE



I wouldn't know. I work on my puzzles a few hours per evening, a few days per week. But I work on about 10 different projects simultaneously.



I only used (fine white) Milliput once, for my first 2x2x3. I now only use black Apoxie Sculpt. I think the latter is a bit easier to work with. But I'm not sure. I prefer it, simply because it's black (and cheaper).
