Specifications of Melinda's 2x2x2x2?

[Matthew Hinton]

Hello everyone, since I don't have the kind of budget to get a physical 2x2x2x2 cube 3d printed, and since I have a woodworking workshop in my basement, I'm going to attempt to build one in stained maple.

I need to know what the dimensions of the 3d printed one is, and what the back of the sticker (inside of the hypercubie) looks like with the magnet holes. If anyone could donate some numbers or pictures it would be very welcome.

Thank you.

[Robert DuBeau]

Haha not the best choice to draw on a paper towel but this is the sketch layout for a Hypercubie. You’ll want your magnet holes to be drilled identically on all faces. The diagonal lines and color letters show how to paint a typical face. Half red half blue, etc. I don’t have my physical cube handy and don’t know the dimensions but something close to typical game dice size would be about right. Very important to match polarities and colors properly across Hypercubies. Don’t take my color/polarity example as correct. Ideally match to an existing Hypercube. Just a rough sketch.

[Matthew Hinton]

Thanks, that helped. But it would make it easier to see how close to the edge the holes have to be drilled. I know how to do the polarity from the chart posted at shapeways. Thanks for the advice!

The cubies are 19 mm^3 The magnets are N38s and are 0.5 mm from the surface.

Thank you, that is all I need to know

Would anyone buy a wooden 2x2x2x2?

This first one I've decided to paint but afterwards I might do one with veneers of the attached photos' colours. If anyone would buy them I could make more.

To me, wood feels and looks really nice in the hands, and may not compromise speed-cubing ability at all. I've got to test it first though. I'll post pictures once I've got a good start on it :)

Sorry, I meant to post this picture instead of the 4 maple colours:

Is there any way to get the stl file for Melinda's 2x2x2x2 if we have access to a 3d printer? I'd like to 3d print one as well for a reference on the magnet strength but do not want to pay the price for ordered printing.

Thank you,

Matthew

I'm sure there's a market for high-end wooden versions like you imagine, or at least there will be once there is a cheaper mass-produced version. I have no problem with you making your own and selling them to list members with no mark-up. If you want to sell a for-profit version, I would prefer a profit-sharing arrangement whereby you let me sell them alongside my mass-produced version as a high-end option.

Not only would I like having a high-end wooden option, but I think wood could be a superior material to any sort of plastic, because of its softness which I think will make a more satisfying snap and a more satisfying feel while operating it. It may also make the puzzle more difficult if it's possible to end up with it solved but the wood grain misaligned. That would effectively make the faces into 3D picture cubes.

Finding 8 suitably contrasting woods may be difficult. One option may be to just find 4 contrasting varieties and making opposite pairs by staining them so you have light and dark versions of the same type along each of the 4 dimensions. That way you get a maple dimension, a walnut dimension, a teak dimension, etc.

I believe the current version is simply not amiable to home printers. Several people have tried and failed. I'll be happy to let you try too. If you succeed, I only ask that you not share your models with others, and that you only make them for yourself or as gifts. How does that sound?

I am replying publicly because I want to extend the same offers to all list members interested in making their own. I really like what some people have done already, though I don't think any such solution ever will top Marc's foam & honey cube for creativity!

Thank you, I would like to try to print my own, you can be assured I will not share the model with anyone else. Could you send the model to my email? I can download and print my own from there.

[Grant Staten]

What printer do will you use? The pieces are too intricate for normal home printer, I thought I could do the same thing, but ended up designing my own models with a different method of putting them to

*together. Sorry I forgot to finish the last word in that

[Matthew Hinton]

If the wooden version turns out, I'd be happy to sell them alongside your mass produced cubes. If possible I would like to sell them for at least $100 CAD, as they require: Machining 16 cubes of maple, drilling 384 magnet holes, inserting 384 magnets. cutting and gluing 192 triangular pieces of veneer, staining half of those pieces, sanding, and varnishing. I plan to use these magnets, as the veneer with be slightly thicker than 0.5 mm and wood will a higher strength of magnet. They are also less expensive than the D0402 magnets in the mass produced version. Expenses for veneers and magnets should play a part in the overall cost. It may be a while before I build one so don't expect a cost estimate soon.

Thank you,

Matthew

I was planning on using a Lulzbot Taz 5 dual extruder, but you're probably right that it's to intricate. I was thinking that if i had the model I could alter it so that the magnets could be put it from the outside and the pieces could have thicker walls. I wanted a pre-designed mechanism on the inside, though, to clip the hypercubies together. And for that I'd need the original model.

[Matthew Hinton]

I have chosen the types of wood that I believe will be most contrasting and easy to work with.

Up: Yellow Ocher/Raw Sienna Stained Maple (Yellow)

Down: Raw Maple (White)

Right: Raw Bloodwood (Deep Red)

Left: Burnt Sienna Stained Maple (Pink/Orange)

Front: Raw Cherry (Light Brown)

Back: Raw Purpleheart (Purple)

Inner: Semi-Black Stained Walnut (Semi-Black)

Outer: Raw Walnut (Dark Brown)

[Matthew Hinton]

On the other hand, I might substitute Teak for the Burnt Sienna Stained Maple; I'll have to check it's colour against Cherry and make sure it contrasts enough.
