Has anyone dealt with 3D printing patented designs?

Has anyone dealt with something like this? I'm not sure what my options are.

3D printing patented designs. I've been dealing with this for about 7 weeks now and the situation isn't improving.

This involves original creative work over the past 34 months. I do not have documentation proving my ownership and timeline.

Do I have a strong case? What should my next steps be?

Following this thread — Same boat here, please update us on what happens lol!

Been there. Here's what I learned.

I ended up having everything documented, which cost about $3-6 but saved me a lot more in the long run.
