ZipMacPlus_Chernobyl_Edition™ The warming and machining characteristics of the material used for #4 lead me to believe that it's Polycarbonate and not Acrylic. I didn't know those things were made of plastic... No wonder it blew up }🙂
Joke aside. Yup, you brought it back from the dead. Now I must go franken-thread-ing too.

edit: LOL! You beat me to posting. ISTR seeing pictures of a Mac case "slumped and scorched" in a fire way back when. I'm hoping to find a post I made several years back in a member's topic about the black plastic fillets he made for the LCD to fit the curvature the Compact bezel. Those could be printed in sections to be combined with my formed plexi bubbles. As far as I'm concerned, absolute clarity with "floating" LCD panel in all its glossy glory would be perfect for showcasing things that have no business appearing behind the CRT face of a compact. [😀]
@Byrd: Very cool, that teflon sheet over plaster buck trick is new to me, thanks! Any other tips you can share about any of the molding processes in use there would be greatly appreciated.
I'm looking forward to playing with my CRT setup again using much thinner plexi, but that costs money. I have what amounts to an unlimited supply of the 1/8" variety available as scrap for chump change. Time is what's missing from that equation.
As an aside, I've played with sculpting clay to make a down and very dirty negative mold of the corner of a monitor case. With an ABS in MEK dissolved thick slurry I've experimented with the notion of "laying up" fiberglass cloth to reinforce case parts much too large for printing. Even the "Snow White" grooves came out about as well as could be expected.
