Anyone 3D printing a general knitting kit and notions?

I have a fantasy about getting a 3D printer and making my own stitch markers and sock blockers. Anybody with knowledge of 3D printing for knitting or suggestions for the best/largest printers for a set of sock blockers would be appreciated. Although I’ve seen several stitch marker designs for 3D printing online, I’m constantly interested in more patterns and design advice. I’m not overly concerned about problems with proprietary software because I have both a Mac and a PC.
