Who here is making money 3D printing?

I am a hobbyist, and my job will probably never require me to design and print anything for work.

I do really enjoy the process of conceptualizing, designing, and printing, and have done so for myself and some close acquaintances.

I've spent many hours/days learning the tools of the trade and was wondering if there was an opportunity to make some money as a side gig. Has anyone been successful doing this, and how did you go about it?

Here are a couple of my early designs, I plan to upload more once I clean things up a bit.
