Pretty much used Cura 2.5 default settings. Matterhackers Red Transparent Red PLA. Did use PVA support and printed vertically to give better print results (no circular steps on subtle curves). Painted with a combo of Metallic Paint (Main Frame and internal Frame accent) as well as Fingernail polish with Gold Testors Model paint for accents and a really, really fine brush. Why? Because it can be sparkly and give subtle color transitions as your viewing angle changes. I like sparklies and twinklies.
Printed at default 0.2 MM on UM3_X
Used "Hollow Out Object" in the experimental tab which will hollow out the object as well as create a support structure for the internal overhangs.
Cribbed from Bugs Bunny image Bugs Alone) found in search engine (Style Guide art). Used a Looney Toons Font (Free). Designed the Frame and such around cribbed style guide art. Painted base parts but left main red area alone to allow light to transmit through.
Made for a very nice young lady who just earned her Doctorate.
