The ones I have seen usually come in a set of 5. Clear, yellow, green, red and black. I bought two sets in the 90's that had six, one being blue. That was a nod to one of the colors in the book.

Made another revision to the crystal. I had remembered Calico 1997's photo of the caliper measuring a crystal, in fact, I used those measurements for the final size. However, in looking at the photo again, I decided that the edges of my 3D model might be too steep. I scaled down the facet in the outermost petal facets so the sides have more of a slope. It's still the same height.

Just throwing out the idea, but consider glow in the dark UV powder.

I use the stuff in resin cast all the time.

Even in regular light, once it gets charged up, it glows. It looks much more brilliant/intense

Wow those came out great

renders. Not real.

Got it !

More renders, this time with simulated reflective backing.

Now real. A lifeclock positive and a 5X5 grid lifeclock negative mold. Printed through Shapeways.

A shot of a lifeclock in my palm, then with aluminum foil in pack. A shot of the mold, and the a couple more of the mold, and then with quick-and-dirty pressed-in sculpy copies.

Are you selling these or the ST file so I can print one

I can put mine in the free STL section. I've just got to track down which version I left off with. I haven't worked on mine in a while.

I finally discovered UV-hardening resin. I tried to do the 2-part casting resin in the mold I had 3D-printed. I added red pigment powder that I had on-hand, but it made the crystal I cast opaque. Plus the resin stuck to the mold badly, and I had to pry them out when they were still soft to remove them from the mold, and resin I didn't pull off is now hard and fast on the mold. I used vaseline as a release agent but it didn't work.

Then at the craft store I discovered UV-hardening resin. They only had clear. I did a test and it worked really well. Even as I was exposing it to the UV light as it hardened some of the facets started to pop free of the mold. The mold plastic is slightly pliable and I was able to bend it enough to pop the copies free enough to pry out with an exacto knife.

Something that might be an issue is the UV resin puts out a lot of heat as it hardens, which has made the 3D-printed material turn a bit white. I don't know how negatively that will affect the mold.

I'm hoping I can find the UV resin in colors.

Great job! Keep up the good work.

Looks like my production made ones!

5 colors. The colored ones have mirrored mylar on the back. Because I snapped a few in half pressing them into my palm I have given them a little more thickness. Turns out it also has a better look with the reflective backing than the thinner ones. Oh, and I've been using 2-part resin rather than UV-hardening resin. With the pigment, the UV light couldn't harden the entire thickness of the resin. Also, it's so viscous that I couldn't get the bubbles out after stirring in the pigments. The two-part resin, I will say, is a pain to get out all the bubbles, but I can't afford and don't have the right living area for a "pressure pot."

No need to renew mine..Tom Cruise already said I was a clear

Unlike those, mine are radially symmetrical. I wanted "perfect" ones, because I am anal that way, and because I don't want people to mistake these for production copies.
