King Flexi Rex. Both fixed jaw and movable jaw stl files are provided. The fixed jaw Rex is easy-print, so that you can try it first. For movable jaw, jaw gaps 0.30mm(da Vinci Jr.1.0A & CR-10S) and 0.50mm(da Vinci mini w) are suggested for 100% printing. Try test-gap things (Rex pencil top https://www.thingiverse.com/thing:3263585 or Rex keychain https://www.thingiverse.com/thing:3395707) first to ensure the acceptable jaw gap of your machine. Larger gap can be used for smaller-scaled printing, and smaller gap can be used for larger-scaled printing.
