Modular Quick-Release Ratchet Vise – 80mm Jaws & Ball Joint Mount

A versatile, fully 3D printed modular workbench vise designed for modeling, electronics, soldering, and light DIY tasks. It features a fast dual-rack ratchet mechanism—simply push the movable jaw against your workpiece with your fingers, and squeeze the rear release levers like a clothespin to open it. Key Features: - Fast & Fine Ratchet Mechanism: Dual-sided offset teeth provide half-pitch precision (1.75 mm steps) and reliable locking without tedious screw turning.

- Modular Mounting System: Choose between a heavy-duty desk clamp with a ball joint (compatible with a straight extension tube, side boom arm, or direct head mount) or a rigid dovetail mount.

- Single-Nut Ball Joint: Locks firmly in any angle with a single large hand-tightened collar nut.

- Interchangeable TPU Jaw Pads: Slide-in dovetail pads available in two versions: flat ribbed pads for general gripping and V-grooved pads for round objects like rods, dowels, or pens.

- Fully Parametric: Includes the complete OpenSCAD .scad source file so you can adjust tolerances, jaw width, rail length, or export test pieces (test_ratchet, test_fit, test_thread, test_socket) before printing the full set.

Recommended Print Settings: - Material: PETG is strongly recommended for the main body, clamp, and especially the ratchet slider (the flexible hinges require PETG's elasticity and durability; PLA may creep or wear faster). Use TPU (95A) for the jaw pads (tpu_pad / tpu_pad_v) and the desk clamp foot (desk_pad).

- Perimeters / Walls: 4–5 perimeters for high strength on the clamp, threads, and ball joints.

- Infill: 25–40% (Gyroid or Grid).

- Supports: Required on overhangs in a few parts (such as the upper arm of the desk clamp and ball joint cutouts). Auto-generated supports (organic/tree supports recommended) work well.

- Pins: Print the Ø3 mm locking pins (pin_head, pin_boom, pin_stop, pin_dove) lying flat horizontally for maximum shear strength, or substitute with standard M3 screws / 3 mm filament pieces.

Assembly Tip (Ball Joint): - Snap the ball plug into the socket without the collar nut first.

- Slide the collar nut over the straight stem and thread it onto the socket.

- Attach the vise head or boom arm onto the stem and secure it with the Ø3 mm locking pin (a drop of CA glue on pin_head and pin_boom is recommended; leave pin_stop unglued so the slider remains removable).
