I've seen several tools like this, this is my take on it. Designed it partially because I like to make my own things, and partially because I wanted to see how the Tornado handles the kind of support needed. This will hold up some scroll saw art pieces for me for both staining or painting, usually, nothing very heavy but I made it really rugged anyways. The points are very, very pointy. This is still very much a thing in the 'development stages'. The end result for me was a bit edgy, but perfection is not my goal here. The edges may not be perfect, but they are going to the shop and will have paint and stain on them in no time.

Please note: the model is 25mm, so you may want to scale it up. I scaled this one to 50 mm for the prints in the photos, it works OK. The scale is going to depend on the size of your project of course.
