Why it can work

  • Estimated $43.91 profit per print hour
  • Low brand or licence risk if the design is your own

Why it might fail

  • Thin public evidence, so treat these numbers with care

Be aware before you sell

You own the CAD you create, so state in your terms who keeps the file. Copying a single part for repair is usually lower risk, but check design rights and refuse branded logos. Etsy asks for your own original design, so a licensed file may not qualify.
