Remix of screw component (pin.stl) from "Solder station - third hand - helping hand v3"

Remix the `pin.stl` component (the bolt) of "[Solder station - third hand - helping hand v3](https://www.thingiverse.com/thing:5253842)", the original pin resulted a bit too narrow on my precise printer, my remix also: - increases screw XY size by 4% (soldering-pin-remix_screw4-iviar.stl) to adhere more to the nut and reduce unscrewing possibility by moving the arms. There is also an even tighter 5% screw .XY increase (soldering-pin-remix_screw5%-iviar.stl) - produce about 2mm shorter base because there was no benefit to have a big screw head - leave space line for a coin usable as a screwdriver - make the head of the screw smoother (intersected with a cone) - save 10% filament with the same function, so it is lighter and quicker to print (about 25 of this needs to be printed) - keep the possibility to print without support and provide greater first layer adhesion area (except that is split in two by the the coin-as-a-screw invite) PS: I added also a thinner nut remix `nut-16mmExt-remix-iviar.stl` making the side hexagonal large 16mm, this nut prints without retraction in 0.33m with 100% infill (I conserved the identical nut filet, suggesting 3 perimeters and with PrusaSlicer 2.4.0 it prints without retractions on 0.4mm nozzle, a previous attempt with 15mm side to side version had retract so I omit to publish it). Printing the required 26 of them uses 8.66m of filament saving half the time with no retraction, compared to 12.5m and you with it you can use a 16mm wrench.
