Your download includes:

• Complete 3MF print files for both sizes.

• Illustrated PDF assembly and use guide, including close-ups of pulley installation and twist-lock operation.

Hardware needed:

• Large: M3 × 12 mm retaining screw.

Hardware, rope and other training accessories are not included.

Printing and assembly

Print the supplied files at 100% scale—the sizing is already applied. Select your printer and filament profile, then slice before printing. Follow the included guide and tighten retaining screws only enough to secure the parts while allowing free movement.

Use alongside your other tabletop rigging props to demonstrate rope-grab placement and hauling-system operation. A complete 3:1 setup requires appropriate rope routing and a separate progress-capture device.
