Bowl forms for pottery

This is a pair of bowl forms for making simple bowls with a slab of clay. There are two sizes, one that's a bit narrower and one that's a bit wider. Both molds have a spot to attach the base which screws in. The screw works with both sets and if I ever get around to making other shapes will work with that base as well so you can swap between them as desired.

Print it with as little layers showing as possible so that the layer lines don't transfer to the clay (or do, it's your art). I found it helpful to get filling primer and spray the forms a few times sanding in between to get them smooth. I also found it useful to put a mold release on the form before applying the clay so they release nicely as they dry. I found a very small amount of cornstarch just run lightly over the surface worked well.
