Assembly Instructions
Minimal preparation is required to assemble the freshly printed parts for precise operation:

Preparation of Parts:
After the parts are finished, follow these steps:

Insert the two pins into one part of the stock as shown in the reference images.
Apply glue to the joint area and press the two parts together firmly to form a single durable unit.
Sanding Joints and Locks:
Use a file or sandpaper to smooth out any imperfections in the joints and locking mechanism caused by printing.

Installing the Lock:

Use any standard spring with a compressed height of no more than 5mm and a diameter between 5mm and 9mm.
Insert the spring into the handle.
Push the lock down and secure it with a 1.75mm filament piece. Ensure the lock can move down into the handle by at least 3mm for smooth operation.
Securing the Filament:

Trim the excess filament, leaving approximately 0.5mm protruding on each side.
Heat the protruding ends with a lighter and press them flat for a secure fit.
Finishing Touches
To enhance the appearance and functionality:

Lightly sand the assembled stock to remove any remaining printing imperfections.
Apply texture paint to minimize layer visibility and achieve a clean, professional finish.
