Now, with future technology, we can create objects that are incredibly customized. Let's apply this to...jewelry! Hand candy! Finger blingers! Digit...smidgens...
OK, I'm out of metaphors.
Let's do this!
Step 1: Choose Material for Your Ring
You could go with wood ply, a common laserable material, but that would leave a dark brown edge as the main part of the ring that would be visible. Sanding that off would only reveal ply edging.
An alternative is to make the ring out of acrylic, which comes in a wide range of fun colors.
Another alternative is to make the ring out of solid wood & then sand off the burned edge. This would leave an awesome wood grain, if you choose the right wood.
I chose this route. I found a nice scrap of roasted wood...an interesting new process that turns wood brown throughout. Used to make less expensive woods turn a rich deep brown shade. Raaaaad.
Step 2: Choose the Width of Your Material
Step 3: Create a File & Laser Cut the Material
Based on my ring sizer, I made my ring file with an interior diameter of 1.78cm, or 17.8mm. I then added 2mm on each side to make the outside circle, which ended up being 2.18cm, or 21.8mm. So, my ring ends up being 2mm thick.
Your settings for this will depend on the power of your laser, user discretion is advised, always ask a laser elder for help.
Here we have the Awesome laser of Breath-taking Beauty, at work. I lasered this baby at TechShop, land of the free, home of the brave.
Step 4: Sand the Edge...or Not....
Now, time to reassess my materials...
Step 5: Choose a New Material, If Necessary
Step 6: Admire Your Handiwork
You could make, like, a bajillion of these in different colors, for different outfits, or stack 'em, or...or...whatever you can dream of. The world is your oyster.
Congratulations. You are now the proud owner of a custom, perfectly sized ring.
