I posted the end result here: Acrylic 8-bit Heart Necklace
This post is the design files:
First the jig (I cut this on PG medium draftboard) set everything but the text to cut (the text is engraved)
The center is black 3mm (0.118in) acrylic set everything to cut. I bought some cast acrylic a while ago, but used PG medium black acrylic settings.
The outside is red 3mm (0.118in) acrylic same settings as the black center.
I bought the following:
2mm x 1mm magnets (Outside): https://www.amazon.com/gp/product/B07BHF3X86/
3mm x 1mm magnets (Center): https://www.amazon.com/gp/product/B07BHHNBWQ/
Metal Ball Bead Chain: https://www.amazon.com/gp/product/B075FS4YT7/
You’ll also need some glue for acrylic, which I picked up at my local Tap Plastics
If you make one, please post a photo, thank you!
