How the score adds up
Demand and legal risk come from the niche Tool box system add-ons. An idea to test can score 69 at most until someone has seen it for sale.
Why it can work
- Strong public demand signals
- Seasonal demand: Father's Day and Christmas gifting are likely, based on my judgement.
Why it might fail
- Under $2 estimated profit per print hour
- Milwaukee and Packout are brand names, and no takedown reports were found, but use 'compatible with' wording and no logos
- Thin public evidence, so treat these numbers with care
Be aware before you sell
Many Packout files sit on MakerWorld, where selling prints needs a valid licence, so check each file or design your own. Milwaukee and Packout are brand names, and no takedown reports were found, but use 'compatible with' wording and no logos. Etsy asks for your own original design, so a licensed file may not qualify.
