Support Free Cactus

I had some green PLA filament left, and I wanted to try to do something that would be challenging to print without any support. So, here's a little cactus (42mm high). Quite simple (and extremely useless) but interesting to print with no support whatsoever (you may even watch the timelapse video of the printing process). It don't know if it qualifies as "art" but I think it's kind of decorative. :) Edit : I've also designed a support free printable little pot that perfectly fits this cactus! ;)
