I am not a fan of the bag brass catchers so I made this solid brass catcher (picatinny mount)
After printing mount A - Screw a long 3mm screw into the "mount rod" (For lack of a better term) to strengthen it for repeated mounting and unmounting
Install picatinny mount pieces A and B with the mount rod on the ejection side (3mm screws)
Slide the catcher onto the mount rod. Easy on and off so you can remove / install quickly and without tools.
When the catcher fills, just flip it up and dump the brass, flip back down to use again

This is a work in progress as I do not know how heat will impact the unit in the field.
I am going to print with PET-GF (15% Glass Fiber Reinforced) as it has a 400 degree melting point after printing,

If it works I will build one for a 15
