Ready to go, 3D Printable multi-tool. V5, V6, & V8

The goal was to print a multi-tool in one go, featuring mechanical parts that didn't require assembly. V5 boasts a 1/4 bit driver, Phillips and flathead screw heads (though they're not impressive due to being made of plastic), a rough box cutter, and a quick-release mechanism for lanyards. V6 includes a bottle opener that works but is similarly marred by its plastic construction, at the cost of the two arms. In contrast, V8 offers a significantly improved design for the bottle opener and strips away all other functionality except for the cutter.
