Low profile machining vice for sainsmart gemnitsu 3030 prover max. 

I printed at 100% infill with pet - cf filament. It's super solid like this but probably way over kill. I would recommend printing the jaws solid since you can machine them a few times if you happen to mill into them. 

Print - 

1x vice base

2x jaw1

1x jaw2
 

Hardware needed -  

4 - m6 x 1 x 10mm socket head cap screws (attaches vice to machine use longer if you have spoil board installed)

6 -  m3 x 25mm machine head screws (fine or course)

9 -  m3 nuts to match your machine head screws (6 for jaws + 3 for clamp tightening bolt)

1 - m3 x  45mm (or longer) for clamp tightening bolt.
