Would anyone be kind enough to post a guide to creating a Dino cube from a Rainbow cube? From searching through the forums I understand that there may be more than one method, such as using sheet plastic over top of the corners or building up the corners with plastic resin.

I'd like to try to build my own Dino Cube. This would be my first attempt at a mod.

Thanks in advance!

Thanks juanan, i've been wondering the same thing for a week or so =]

The picture seems to imply one where you can also twist the corners. Certainly looks interesting and would not be too difficult with the proper materials. Has anyone done this?

That is actually the Lattice Cube by the same builder as the Void Cube.

It's actually harder than one would assume because the corners must be embedded deeper into the mechanism so they don't fall out in mid turn.

With the help of those who replied I have managed to make my first mod. I am happy with how it turned out, even if the spacing between corners is obviously fairly large. I am now waiting for my sticker sheets to come in so that I can add stickers.

The corners are cut out of white translucent acrylic sheets on a CNC machine, they measure exactly 4 cm squared. A diagonal was cut to half depth which allowed me to bend them 90 degrees using heat. I then painted them in black and attached them to the Rainbow Cube with acrylic cement.

See attached pictures for details.

That's really cool. And it looks awesome for a first mod. I've been wanting a Dino Cube for ages, where can I get a Rainbow Cube to mod?

Puzzle Shop Torito has rainbow cubes. I haven't gotten one but I heard their good quality.

I got my Rainbow Cubes from an eBay seller called ukcubed, but the paper insert that came in the package makes reference to another eBay seller named www-puzl-co-uk. I am assuming they are one and the same seller. Anyways, the product was excellent and delivery was prompt.

Where did you buy your acrylic sheets?

I aquired the plastics locally through an aquaintance who also helped me with the access to the milling machine and other equipment - I used what was available as scrap plastic. Had I been forced to go out and buy material, I would have bought matte black acrylic sheet so painting would not have been necessary. Since you are in the US, try:

They seem to have all kinds of plastics in all sizes. The one I used is 1.6 mm thick (0.063 inches).

i just finished building a dino cube also, and it just dosnt turn very well without the spacing.
i think that it looks pretty good for a custom build, good job lefty

It looks very good. Be precise with the stickers. With good stickers I'm sure this puzzle will look excellent.

Is there a way you could (say you had another Rainbow Cube to mod) reduce the gaps on the puzzle easily?

Never the less it looks great. Like Thomas said, a good stickering job can really make a great puzzle.

That's what I am noticing on mine. Had my spacing been any tighter, I would not have been able to turn it. Because of the added height, it needs the extra spacing in order to allow the original turning dynamic of the Rainbow cube (which barely has any spacing). I'll be sure to be very accurate with the stickers, and will post new images when I am done.

Can we see a few pictures of your mod daddrivemecrazy?

i thought about this and i believe you can reduce spacing (im not sure about it being easy)
look at the bottom left picture in the first box. if you were to just extend the triangle faces (like the picture shows) instead of gluing plastic sheets on the square sides, it may help the pieces to not rub against each other so much. i actually tried this method and seemed to work fairly well. i just had one problem, it looked terrible and all the tiny pieces i made kept falling off. so i restarted for the third time using the same method as lefty, and in doing so ended up with the same problem.i will post pictures, but i am planning to wait until i get stickers.

You could have beveled the edges of the puzzle to minimize the gap. Once the pieces are folded, you could lay the piece on its edge so that the piece is contacting the sandpaper in a "V." Give it a few quick rubs. Then "tilt" the piece over so you hit the other "V." A few more quick hits. Repeat with several grits, from about 100 to 600 and you would have a very reasonable working edge. That would allow you to tighten up the tolerances a little.

this may seem naive but i cant seem to find a place that sells rainbow cubes could someone give me a link

its mentioned above, I would recommend reading the whole topic, especially since this one is only 1 page, before you post.

And finally, as promised, pictures of the puzzle with stickers. I cut these myself with scissors and found that leaving the corner points sharp looked better than rounding them off. Sticker sheets were purchased from cubesmith. I went with the standard cube colour scheme.

It looks great! nice job

It looks pretty good!

Thomas

well done
