This is a simple stencil with a french-curve esque edge, dot grid, angles, and ovals that I made and have been using for graphic design projects. It seems simplistic, but I've found it very useful for fun lettering and branding projects. My version is laser cut, but here is a printable version. Fits on 180mm x 180mm plate. Check out Ed Fella's work for art made with similar stencils.
Edit: Added a thinner, 1mm version as well
