So, this isn't real exciting (it's just a tiny box), but it's my first successful object with my Zen, and with CNC in general, so I'm proud of it!
Made of MDF, not anything pretty. I did some light sanding, but the cuts really weren't that rough. Total cut time for both pieces was about 1 hour and 10 minutes. Cut with a 1/8" double spiral flute Dremel bit, Dremel set at 35k RPM, feed rate 300mm/min, cut depth was 2mm for most of it.
