I had some success with the production of leaves using this method and wanted to see if it could be applied to flowers. Assemble all parts. Then, heat the petals and bend them. I've also found this is a good way to burn your fingers, so be careful.
"Flower Petal 1.stl" and "Flower Petal 2.stl" are not the same. One of each will need to be printed.
"Flower Stem.stl" will need to be printed twice.
You may need to add a Brim to the stem.
