Rotating, Tilting, and Weighted Vise (Sand Filled)

I was thinking about picking up a Panavise to help with some of my soldering and other project work, and then decided to try to model out something that could be 3D printed instead.

My goals were to create a vise that felt nice and smooth (with little “play”) when rotating, tilting, and tightening - while also being heavy enough that it could hold a piece in place without having to be bolted down.  Some helpful grooves are also included in the jaws to help with holding PCBs, etc.

All parts have been carefully designed so that they can be printed without supports, and no glue is needed for assembly.  Any layer height or nozzle size should work fine for printing (I used a .2 mm layer height with a .4 mm nozzle).  For at least the jaws, clamps & pivot shaft I'd recommend increasing the “Vertical Shells → Perimeters” setting to at least 4 and the infill to at least 50%.  In addition to the STLs, I'm also attaching a 3MF file that includes all of the parts in their recommended orientations, and shows the settings I used to print the one shown in the pictures on my Prusa Mini.

Update (2023-05-22):

For those where obtaining M6 bolts may be more challenging, I've now uploaded a second set of STLs into a folder with name “Quarter Inch Bolt Version” (and included versions of the vise jaw that should work with ¼ inch bolts of several different standard lengths.) 

Update (2023-06-16):

There is now a speed control handle available as a remix for this vise as well.

Assembly Notes:

1. For the vise clamp you'll need a standard M6 bolt, and I've provided the STLs for three different lengths: 100mm, 120mm, or 140mm.  The one shown in the pictures is 120 mm.  (If you'd like to use a different size, that's easy to do, just let me know in the comments!)
2. An M6 bolt is also needed for the pivot clamp, I used a 30 mm.
3. Slide the M6 bolts into the “Knob” parts, and then secure them with a “Knob Cap”.  The cap is intentionally designed with only a small amount of tolerance so that it stays on tightly, and therefore may require a couple of taps from a hammer.
4. Place an M6 nut in the space provided in the  “Base Bottom”, slide in the “Clamp Left”, “Clamp Right", and “Pivot Shaft” parts, and then attach the “Base Top” piece using 20 mm M3 screws.
5. Slide an M6 nut into the space provided on the “Mount Jaw', insert the ”Rail Jaw" piece (threading on your chosen M6 bolt), and then attach the “Rail Stop” using 8 mm M3 screws.
6. Attach the assembled jaw to the pivot shaft using a 12 mm M3 screw.
7. Fill the vise with sand (pack it in nice and tight, the heavier the better!), and then screw on the “Base Plug” piece.
