Brass Catcher (AR10 Compatible, No Hardware Needed)

thingiverse

Remixing Wormskill's brass catcher design, I created an upgraded version that doesn't require any hardware and is fully compatible with AR10 rifles. To securely attach it to the picatinny rail, simply use a small hair tie or rubber band. I successfully printed this design at 75% infill, adding supports under the rubber band catch ledges to ensure stability. In Cura, I blocked supports all around the bag retaining edge to prevent any potential issues. Although there was some stringing, I chose not to remove the supports from the entire piece to avoid any damage. To minimize the risk of breakage during 308 recoil, I opted for extremely high infill printing. This extra reinforcement helps prevent the small cross braces that slide into the two pieces from snapping or breaking apart.
