One of the projects I wanted to do with my Glowforge was reproducing movie props. I found plans for a Hal9000 model on Thingiverse ( Thingiverse Hal9000 HAL 9000 Replica by pburgess - Thingiverse ) that gave me proper cutting specs. It also referenced additional electronics on Adafruit (which I’m still deciding whether to add or stick with a basic bluetooth speaker.
The results so far have been thrilling for me. Cut out of black acrylic, and then side supports were spray painted metallic silver. The “grill area” was cut, sprayed, and then put back in the 'forge to great the speaker “grill”.
The whole piece is then held together by series of nuts and bolts. The Hal logo and eye are currently paper printouts, but will look at printing logo on photo paper for more gloss look, and getting a button eye from Adafruit to get more of the rounded look (plus potential for electronic enhancements).
