Just Some Ordinary Concrete Cufflinks

Featured
I've been playing with 3D-Printed concrete molds for some time now and decided to try my hand at creating some cufflink molds.  I also took this opportunity to give AGT's (Ambient Glow Technology), glow sand products a try.  Here's what I came up with.

Step 1: Materials and Measurements

Materials needed:
  1. Caliper or Ruler of some kind
  2. Cufflink Backs
  3. Concrete (Quickcrete 500, Portland Cement or Mix of Portland / Sand)
  4. Stone Dust (Pool Mix, Marble)
  5. Plastic Covering
  6. Several Containers (Mixing Concrete, Water Bath, and Storing Aggregates)
  7. Water (Mixing, Curing Concrete and Wet Sanding)
  8. Sifter
  9. Strainer
  10. Plastic Spoon and Knife
  11. PAM Cooking Spray (Mold Release Agent)
  12. Flat-Head Screwdriver
  13. Wet/Dry Sandpaper 400/600/1000 - grit
  14. Water Based Penetrating Concrete Sealer
  15. Clear - 2-part Epoxy made for Concrete
  16. AGT Glow Sand
  17. Epoxy Applicator (wooden toothpicks or skewers) 
  18. Carnauba Wax for Concrete
  19. Cloths / Rags / Paper Towels (Carnauba Wax application, Sealer removal)
Optional Materials:
  1. 3D-Printer
  2. Old printed ABS filament
  3. Scissors
First Step
Take measurements of your cufflink backs.  I know there are several different types of cufflink backs out there, I purchased mine from a local hobby store.  You can go as far as making some if purchasing them is not an option.

very cool. I do have a question - Do you think adding the AGT/epoxy mix in a thin layer over wooden cuff links would give you a "wood" look in light and "glow" look in the dark, or is it not transparent enough for the under layer to show through? Or maybe to be transparent enough it wouldn't have enough AGT to really glow?

Hey ardnon, good question! I've just started playing with AGT, so I'm a bit new at it. It comes in different sizes and the sand particles I used have enough "glow" to stand on their own. When I contacted AGT, one of my first questions was if it mixed well with wood glue or white glue and they confirmed. They actually recommended it. I think Gorilla glue makes a clear wood glue version and Elmers white glue always drys clear. If you go the epoxy route, just put a small amount of AGT in your mix and you should be set. You may get a more speckled or starry "glow", and your wooden cuff links may have a few white specks (as AGT is not completely transparent). The best way to find out though would be to contact the company. They're always eager to answer questions. Another recommendation from AGT was to apply the sand in paint or varnish allow that to dry and then apply a clear coat, may be a better route than glue or epoxy.
Wow...this is a very cool Idea. I love your instructable, very well written. Thank you for sharing.
