With all the SG1 folks here the acrylic edge lit portal escutcheon button ring & overlay has been done to death 
Having been there & done that, I figured I’d take @marmak3261’s Mexican discovery (Mayan Sunstone) and turn it into my Glowforge’s Big Glowing Button.
Not knowing how it would translate to acrylic (see my previous post for a wooden coaster comparison of the Calendar and Sunstone designs), I tried with some 0.118" clear cast acrylic I had in stock. I told the GFUI it was 1/8" Proofgrade clear acrylic so I could get initial settings.
Then I adjusted it for my thinner sheet and cut it out.
And with the button glowing.
Pretty cool, but the engrave was a bit coarse. Back to the project file and let’s bump the engrave settings - 675 lpi since I do have to sleep. I should have gone for 1355 as 675 only took a half hour. But the results are most excellent.
And with the button light pulsing.
The button plate has an outer ring that fits around the GF button and then an inner disc that sits on top of the button. I also made a non-engraved outer ring so I could raise the engraved ring’s bottom to be flush with the top of the GF button. That lets the inner engraved disc sit on top of the GF button and be held captive by the outer ring.
I like it but I think if I shrink the ring and the inner disc I can get it set so the outer ring slightly overlaps the GF button. I think that may provide a light path to the outer ring so it glows more when they inner disc is lit up. Since it’s sitting on the button and the disc floats inside the ring it should still let me push the inner disc to depress the actual GF button underneath. That’ll be tomorrow night’s little project before I wrap up a tea house.
