I really could use a resin printer right now, I'm pushing the limit of the detail an FDM can output, but I re-ran the knobs at a higher quality setting overnight and did a little light sanding and painting, think they're as good as they're gonna get. And frankly more than good enough. They're gonna be used in the dark mostly anyways.
Redid the decal, cut it out with a Cricut to get cleaner lines. Don't have any more vinyl so it's on a shipping label sticker for now. Installed knobs. Really pretty pleased with how it looks and feels. Friend is stopping by later to pick it up and help me with the wiring. With covid raging hard in SoCal we're doing distanced collaboration. Not the same, but just the smart play right now.
I'll document it better once we're sure it actually works.
