I am still working on this project, the software and electronic part is complete, but it still doesn't have a proper support. I think that the flower is a little too thick for the TPU level of elasticity, so you may wish to print it with more flexible materials like ninjaflex or to reduce the height of the flower before printing. My tpu version still works anyway, it just doesn't fully close its petals as I would prefer. The stem can be made out of a plastic tube, or something else, didn't think about it yet.
The author marked this model as their own original creation.
