I love making stuff that lights up! This is a work in progress and may not be finished for a little while, but I wanted to post this part because at least one flower is done. You can light these any way you want, or not at all. The stems are hollow so it's fairly easy to run some wire up.  This is an adventure in Blender so I didn't make any fancy way to snap it together as I'm still learning Blender (and that learning curve is mighty long). Just use super glue to put it together.The "vase" they are sitting in is from my voronoi bottle holder project. Future work will include a better vase that has room in the bottom to hide the board and batteries, and I'll probably stick with the voronoi technique because it's awesome. Prints without support. Print the flower part in clear plastic if you intend to light it. The stem is particularly prone to collapse during printing. This is likely because it turns into a gigantic chimney. To reduce the chances of failure, print it with something else so it has time to cool between layers. For example, printing two stems at a time seems to work. Oh and this isn't really a buttercup (I called it that in the filename). It just reminded me of one. Buttercups have 5 petals but I only made 4. Maybe there's another flower that matches it more closely but I just couldn't think of it at the time.
