Solder Screw Fingers

I needed to tin some wires & came across this idea. After looking at the design, I realized I could add some machine screws to the fingers to hold the wire better & dissipate any heat with the metal screws. I made 3 versions, one with just 2 fingers, one with 4 & another with 7 like the original design. I am only using the 2 finger version. I actually used https://www.thingiverse.com/thing:2632340 as a starting point for this design.

I used #6x1" machine screws, but you could also use M3
