Demand and legal risk come from the niche Large wargame buildings and bridges. An idea to test can score 69 at most until someone has seen it for sale.

Why it can work

  • Low brand or licence risk if the design is your own

Why it might fail

  • Under $2 estimated profit per print hour
  • Thin public evidence, so treat these numbers with care

Be aware before you sell

Confirm a commercial licence, because one Etsy designer states that selling prints needs a separate monthly licence and others offer it only on request. Generic buildings carry little brand risk, though sellers should avoid names tied to game factions and should not copy a designer's kit. Etsy asks for your own original design, so a licensed file may not qualify.
