I design and 3d print on my own. I've been doing it since the ripe age of 13. I've gained lots of knowledge in the two-plus years I've been in the hobby.
Working out of my parent's basement with my two machines, I do all of the work myself, and love every second of it.
3d printing has been my passion for nearly two years, and it's very cool. If you are the kind of person who loves making things of any sort, be that functional or fun, 3d printing is for you.
If you ever want to talk about 3d printing, ask a question, or otherwise, feel free to hit me up any time!
