A simplistic flower that puts your unused filament to use. Print the stem and the center and put in any filament you want. The size of the petals can easily be varied to your liking (in the pictures, around 90 cm of filament was used to create the petals).

Simply put the filament according to a picture into the flower center, creating 6 petals. It is a bit fiddly but you will manage :) I recommend to put every other filament line over and under in the flower center. Adjusting the size of the petals is just dragging the filament around a bit until its even and neat.
