I’ve found that the circular sprues on many kits from companies such as Academy, Tamiya, and Dragon make excellent spray-painting stands.
Just snip out the circular sprue along with as much of the adjoining crossbars as possible. A drop of glue on the “feet” underneath the circle will hold it in place and small to medium-size parts can be held securely just above any surface for spray painting.
