Why it can work

  • Strong public demand signals
  • Few sellers compared with other products
  • 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

Etsy's June 2025 Creativity Standards ask for the seller's original design, so check the file's commercial terms and prefer your own design for Etsy. The reservoir idea is generic, so the main risk is copying a named designer's pot shape from a model site. Etsy asks for your own original design, so a licensed file may not qualify.
