🖨️ Recommended Print Settings (For Tooling Strength)
Because this is a functional shop jig that will experience twisting forces and pressure, do not print it with standard decorative settings. For maximum rigidity and longevity, use the following profile suggestions:

Material: PETG or tough PLA (PETG is preferred for workshop life and temperature changes).
Wall Loops (Perimeters): 4 to 6 walls.
Infill Pattern: Gyroid or Cubic (Provides uniform multi-directional strength against twisting).
Infill Density: at least 25%
Top/Bottom Layers: 4/5 layers if you intend to use clamps.
Supports: None required if printed on the bed with the V arms facing upward.

Note: This model was fully modeled and optimized in Onshape.
