I have designed this flower model as a gift for mother's day. It prints in multiple pieces and the whole thing should take just a few hours to print.
I printed from PLA and it came out really well. After you have all pieces printed you will need a heat gun (a blow dryer might work) to bend most of the pieces into shape. This process takes some time to finish. I personally enjoyed shaping the petals, because you can shape them whichever way you want and every single petal is going to be different. You will also need to bend the stem into shape. Be careful with the leaves they are tiny, but once you shape them they should hold pretty well, while still being flexible, which gives them the illusion of being real.
After the bending process I spray painted the petals red and the stem green. Then you will need superglue to glue the petals to the stem using the stem connector and the peg piece. I have included a picture that shows how to put the peg and the stem in the stem connector.
