I wanted to make a cool little name tag for my doggy and started looking around to see what I had around the house/workshop. It ended up being a pretty fun and cool little weekend project!
You can use any variation of parts. This is just what I used:
-Old watch parts
-Metal film resistors
-Diagonal side cutters (wire cutter)
-Drill with a small bit
Step 1: Add Backdrop
For the backing behind the letters, I used a bunch of old watch parts I had laying around, but you can use pretty much anything you want as long as it fits inside the bottle cap.
Mix up a bit of epoxy glue, and apply it to the inside of your cap. Then, use your tweezers and arrange the pieces of your backdrop! In my case, watch parts. Allow the epoxy to dry for a few minutes.
Step 2: First Layer of Resin
Now, just because my watch pieces made for an uneven surface, I decided to fill the cap about halfway up with casting resin before making the letters.
Mix your resin as per it's instructions and fill the cap just enough to cover your backdrop so when it dries, you'll have an even, level surface to work with. Most resins take about 24 hours to cure.
Step 3: Make Your Letters
This step can vary greatly depending on what you want to use to make the letters. Here's what I did...
I first took 8 metal film resistors and cut the metal contacts as short as possible and arranged the resistors in the shape of the letter 'M' (my dog's name is Max).
Then I cut a short length of thin gauge PCB wire and formed it into the shape of an 'A'.
I then took some tiny SMD resistors I had and arranged them in the shape of an 'X'.
Before glueing them, I arranged them to make sure they would all fit in the cap.
Next, I mixed some more epoxy glue and applied it to the cured surface of the resin from the previous step and used my tweezers to arrange the parts in the form of my dog's name. This part requires a bit of patience!
Let the glue dry for a few minutes.
Step 4: Final Coat of Resin
Now, mix up some more casting resin and fill your cap the rest of the way up. Be sure to not over fill it as the resin will spill over the sides and make a mess!
Allow the resin to cure for 24 hours.
Step 5: Drill a Hole for Keyring
Now, just drill a small hole through your cap large enough for a keyring to fit and attach your keyring.
Step 6: Attach Tag
Now, your dog can be proud to show off his/her new name tag!
Hope you enjoyed this little instructable!
