You've done well, but your background helps. I've been into 3D printing for a year and am just now getting to the point where I consider myself proficient. It's a very addictive hobby,  but can be useful. My first project (and one that was way over my head at the time) was making a fire extinguisher bracket for my '63 LeSabre wagon.

Currently, I'm making light bars and other parts to turn muscle cars into police cars. I'm at a standstill until I can find a rattle can or brush paint that looks like chrome that will accept a clear coat.

I've considered a resin printer, but really don't have a place to put it. I do like the flexibility with filaments that FDM printing provides, however.
