Not finished yet, but I was so psyched to see the thing actually went together so nicely, I had to share. Building it is almost as difficult as solving it. It took a surprising amount of time to figure out what goes where. I can't wait to paint it!

Thanks Adam, for a great design!

Wow, I've been waiting to see one of these since that golden 3-D rendering.

cnc machine?

Look at the last picture. See the circles?
That means FDM Rapid prototyping.

Looks awsome. Great job. I was thinking of doing that one.

Mmm really cool shape...

Amazing!!
Every mod with a curved surface always pleasantly surprise me!!!

I wonder how big is "long radius"? inside looking? ..... and how to sticker this mod?
Good luck!!

The real models are always the best approach to Shapes, Space, and Symmetry.

Well, because each piece is unique (?) there only one solved state (?) so it does not need stickering (a bit like Fisher's Golden Cube)

Nope. There are many different pieces, but there are groups of similar ones giving more than one solved state.
Specifically, look at the 3 pieces touching the very tip of the egg. They're all the same.

This looks great! Will you put golden stickers on it?

You should make another with colored plastic or some of the plastic coloring powder from alumilite and just not sticker it at all.

Correct. There are a total of 10 different surface pieces (not counting the core and centers). Two pieces are unique (only one of each)- the top and bottom. There are three of each of the other pieces, which are symmetrically distributed around the puzzle. It really is a brilliant design. I can't understand how Adam was even able to make this thing in CAD.


Already have that planned.

I will be ordering some white alumilite next week. I had considered this: http://alumilite.com/ProdDetail.cfm?Category=Dyes%20-%20Fillers&Name=Alumilite%20Metallic%20Powder, but I am not good enough yet with molding to be able to make these pieces without having to sand them. I'm considering trying the split-glove molding method. Drew's method works great for most stuff, but for these pieces, I am having a really hard time making them without air gaps because of the curvature.

If you make one in white, the core should be yellow.

I built one of these eggs in Green plastic (printed from 3dpartz.com as well)...
The puzzle doesn't need stickers, although all gold would look nice...

The puzzle I think is equivalent to a Shepherd's cube... Very confusing and difficult to solve...

I designed this puzzle to be a shape solved version of the Shepherd's Cube. The only exception is that the Shepherd's cube only has 1 type of center piece, where the Egg has 2 types of centers.

Stickering the puzzle would be difficult, but you could achieve a stickered look by masking off the parts so that only the outer surfaces will be painted. Or a nice guillioche pattern with some gold filigree would look nice too...


Now you can unscramble an egg!

Nice cast

For stickers, good paint?

No yoke this is Eggcellent!

Did you stay up all night thinking of that?

My first one finished. Not as nice as I had hoped. The second one will be better. I'm out of alumilite at the moment. As soon as I get more, I will be cranking out another, more improved one. For now, here's my "golden egg".

BEAUTIFUL!

I love it, great work! Could you show us a scrambled picture?

That is truly amazing! It looks so good.

Wow again!

Great, great job. It looks exactly like the rendering!

When I see the improvements in your Square-2 builds I think the next egg is going to be excellent (I didn't want to poach Tony's joke).

As requested, the "scrambled egg".

Man, that was painful scrambling that up. It's gonna take me forever to solve this thing. I tried to just checkerboard it at first, but it didn't look scrambled enough.

As you can see, I had to paint the inside of the puzzle (because when it's scrambled, you see the sides), but no paint has scratched off as of yet. I could not find gold plastic paint, so I used plastic primer, then painted over the primer. Works like a champ.

Whoa! That looks amazing! Great job. Will you make different colors?

The goose that laid that might have had an uncomfortable time!

Good work!

How did you address the grooves in the masters/cast pieces? Did you fill them in or sand them down?

UGH. Sore spot, dude.
This one is still version 1. On this one, I sanded down, and it's still very loose. You can see gaps between the pieces.

I am going to try the ABS liquid weld stuff that Puzzlemaster recommended on the masters. I haven't ordered it yet, and I'm really reluctant to touch the masters, but I have little choice. I tried several things with the copies. I tried mashing apoxie into the grooves, but it's kinda stiff, and you have no idea how difficult that is on a round surface, with rubber gloves.

Dannyb- I do plan to make a few other colors. Definitely white, maybe silver.. Maybe I can make a bunch and put them in a basket for Easter.

Looks really cool

The transformation from rough black to smooth gold is amazing. It looks great!

Regarding the paint not scratching off on the inside of the pieces, perhaps the looseness of the pieces has worked a little in your favour.

another bump. Here are some pics of the egg done right. This is based on a whole new set of molds, created after smoothing out the original masters. There is no rattling in this one, and it turns beautifully. I didn't paint this one. I kinda like it in white.

I just cleaned up some curved surface masters with good results. I used milliput and smoothed it into the grooves. It helps to moisten your fingers and work it into the putty a bit, although I never got quite the right consistency (too thin, or too thick). I didn't use gloves, but had no problems with my skin.

The idea is to fill them about as smooth as you can, erroring on too much. After it dries, sand down a bit from there until you have a smooth surface. I wound up with a zebra pattern on many faces where the black filiments and yellow/grey milliput between them made stripes. I started with 220 grit and worked up to 600.

I'm not ready to post pictures yet, but I am sure once I finish the puzzle I'll try to remember a few pictures of the masters.

Beautiful!

That is awesome. What color is your core in the white egg?

It's a type A core (yellow). But the center cubies are white.

I love the egg. Were did you get the offset skewb in the background from? Did you make it and I just miss that?

What is FDM Rapid prototyping?

This is a quote taken from Quickparts.com:

"Fused Deposition Modeling (FDM) is a solid-based rapid prototyping method that extrudes material, layer-by-layer, to build a model. The system consists of a build platform, extrusion nozzle, and control system.
The build material, production quality thermoplastics, is melted and then extruded through a specially designed head onto a platform to create a two-dimensional cross section of the model. The cross section quickly solidifies, and the platform descends where the next layer is extruded upon the previous layer. This continues until the model is complete, where it is then removed from the build chamber and cleaned for shipping."

If you want a more in depth explanation, a quick google search will reveal a lot. That or looking at some old posts with the search function!

It's not an offset skewb. It's the Hex Prism 1.

Wow, you really fooled me.

At the angle it is sitting at, it really does look like an offset skewb.
