A 3D printed fractal vise inspired by the original seen on a Hand Tool Rescue video: https://www.youtube.com/watch?v=QBeOgGt_oWU
I wanted to make my own version that was:
- Fully constrained
- Printed without support material
- Used minimal filament
- Open source
It works! https://youtu.be/99Qh1oR2A6A

John Toebes has created an assembly of the vise with proper constraints and that means you can virtually animate it: https://cad.onshape.com/documents/a04375fc5dd6de20b79fc182/w/2a6a78f95915396eb3ffce36/e/630372eae2ff8acb648f5026
More details below.
Printer: Rat Rig V-core 3
Filament brand: X3D
Filament color: Diamond silver
Filament material: PLA
All parts corrected orientated for printing without support.
0.12 mm layer height or similar layer for any parts that have a dovetail joint.
0.2 mm layer height for the remaining parts.
TPU for the feet, PLA or whatever you like for the rest.
It is vital that the bottom of the parts are flat and without any elephant's foot.
I recommend printing test parts such as B2 and C1 to make sure of fitment for printing the rest.
D half: 32 in total (2 per finger, 16 sets)
C1 and C2: 8 of each
B1 and B2: 4 of each
A1 and A2: 2 of each
end body and cap: 2 of each
middle body and cap: 1 of each
handle and handle clamp: 1 of each
spacerA and spacer B: 2 of each
8mm lead screw and nut x 1 + 8mm round rod x 2. Leadscrew should be at least 50 mm longer than rods. I used 315 and 365 mm.
LM8UU bearings x 4 (8 mm ID, 15 mm OD, 24 mm length)
608 bearings x 4 (8 mm ID, 22 mm OD, 7 mm thick)
D halves: 1 M3 nut + 1 M3x12 mm bolt (each, 16 sets in total)
C1 to C2: 1 M3 nut + 1 M3 x 10 mm bolt, two short lengths of 1.75 mm filament (each, 8 sets in total)
B1 to B2: 1 M3 nut + 1 M3 x 20 mm bolt, two short lengths of 1.75 mm filament (each, 4 sets in total)
D1 to D2: 2 M3 nuts + 2 M3 x 35 mm bolts (each, 2 sets in total)
holder to spacerA/B: 8 M3 nuts + 8 M3 x 20 mm bolts (total)
spacerA/B to end/middle body: 8 M3 nuts + 8 M3 x 20 mm bolts (total)
end body to end cap: 32 M3 nuts + 32 M3 x 20 mm bolts (total)
Middle body to middle cap: 16 M3 nuts + 16 M3 x 20 mm bolts (total)
Collars: 2 M3 nuts + 2 M3 x 14 mm bolts (12mm works but is is very tight and 16mm works will protrude) (total)
Handle clamp to leadscrew: 2 M3 nuts + 2 M3 x 14 mm bolts (12mm works but is is very tight and 16mm works will protrude)
Handle clamp to handle: 1 M3 lock nut + 1 M3 x 20 mm bolt (longer is ok but will protrude)
