Why it can work
- Strong public demand signals
- Seasonal demand: Father's Day and Christmas gifting, by judgement
Why it might fail
- Milwaukee is a trademark, so use it only to state compatibility, and avoid logo designs such as the emblem-shaped racks seen on Etsy
Be aware before you sell
Check commercial terms on each file, since the common M18 mounts are community uploads whose licences were not confirmed here. Milwaukee is a trademark, so use it only to state compatibility, and avoid logo designs such as the emblem-shaped racks seen on Etsy. Etsy asks for your own original design, so a licensed file may not qualify.
