I got the body printed with JLC3DP’s 8001 resin. It’s only rated for 53°C, so you must be mindful of heat. In this decorative lamp with undervolted, low-power LEDs, it’s not an issue.
I assembled these 38mm 12V LED filaments with brass wire.

Before I’m thrown in electronics jail, I confess that I’m partially committing one of the Bible’s cardinal sins by wiring 4 LEDs in parallel with a single current-limiting resistor.
I argue to the leccy inquisition I am so generously underpowering the LEDs, even if a single one hogged all the current, it would still be fine. Let’s call it a minor misdemeanor.
