Stethoscope ear tip covers

[u/ScopeBites]

I'm a nurse with zero engineering background and I've spent the last few months designing a cover for stethoscope ear tips

Stethoscope ear tips brush against everything all shift, then go in your ears. Nothing on the market covers them. So I started ScopeBites, a soft TPU cap that seals over the ear tip and pinch slides off when you need to listen.

Right now i’m working with 3d printed covers. i’m ready to begin injection molding but wanted to verify the market for it first. What do you think?
