This is a simple two part model of a piranha plant. You can put it into a flower pot next to a “real" plant to make it look a bit more dangerous.

Printing

The heads need supports (threshold 30°) and depending on your build plate the stems might need a brim.

If your printer is capable of printing with multiple colours, you can download the coloured .3mf files. If that isn't the case, just print it with one colour and paint it afterwards, or leave it unicoloured. 

Assembly

There is the actual head and the stem of the plant. They should fit together loosely, so you can decide in which direction it looks. Depending on your use case you might want to glue the two parts together after finding the right orientation.
