This brass catcher mounts on the bottom rail of a pistol.

Only one bolt attaches arm and pistol. Which hole used mounts the arm front or back.

The top section is designed to print with flexible material (TPU). This helps prevent brass from bouncing back out. The base is plastic (ABS or PETG).

Ideally the catcher is centered over the ejection port, with the slide locked open.

A single 3mm nut and bolt was used to clamp on the pistol. I used a couple shorter ones to join the base and arm.

Small zip ties attach the top and base.
