My wife likes cacti, I like 3d printing. I have been making some other clicker things for friends and family and figured I might as well design a little cactus for my wife. I just did some test prints on some rainbow filament I had loaded up and they turned out fine. 

Requires a mechanical keyboard switch, but other than that is all printed. I printed without supports and honestly it turned out fine, especially considering you never see the bottom of the cactus. All you need to print is the pot and your choice of tall or stubby cactus.
