That is a sweet vise which was created by HyMech -but i wanted to go more smaller and down-scaled the files :)
After down-scaling the jaw depth was now just not enough in my opinion and therefore i made some modification to have 5mm jaw-depth.
As the screw itself went small too there is no more handle required (no big clamp force necessary for tiny parts).
I grabbed from johann517's useful G-Clamp just only the knurled Knob and added it to the screw-> fits perfectly!
another modification: slightly bigger slots on the sides
Clamping width approximately max.20mm
Infill Base&Slider: 15-20% with 2 shells with slow print speed
Infill Screw: 100% with 2 shells with slow print speed
depending on how you place the part on the bed some support is necessary
