My 4 year old has a toy that was missing a small piece that is no longer produced and is very expensive to buy. I made the piece (same size and color but different details -- screen, buttons, not undercut on back, etc)). A friend asked if I would copy it for his kids toy (hence my interest in resin casting). Seems there a demand for them. Can I reproduce the piece and sell on eBay? It's a Disney toy. I would clearly say it's an aftermarket add on. What should I know before proceeding? Any advice is appreciated.
Thanks,
JB.
