I started with ABS but gave up after several iterations and warped parts. I'm currently working with PETG and having good success although finish isn't what I'd prefer (takes some sanding). Resin would be great with injection molding supreme, but this is a poor man's attempt at an initial quantity of two!
ABS could be easily used for smaller more uniform parts, just the doughnut shaped bezel requires more stiffening to keep from warping. I would definitely lean towards ABS for most parts as preference.
