Magazine Extension Clamp for Benelli Supernova Shotgun

All the ready available clamps for securing magazine extension were way off of real measurements. That is the reason for me to design my own clamp. I printed it from ABS on Prusa i3. Recommend using another colour though. :-) Print two halves of clamp and mount them on the gun with three M3 screws. Use secure nut if you wish.
