45LC/.410 shotshell sidesaddle mount

Picatinny/1913 rail sidesaddle holder for 5x .45LC or .410 Shotshells. Designed for the Rossi Brawler, but should work with any rail-equipped firearm in .410 or .45LC. 

Print 1x of this model, and 1x “smallside” from the original. 1x M3 nut and 1x M3 screw (M3x30) required. 

My first print of this was in PETG, which worked great until it shattered (hit my thumb under recoil). Re-printed in TPU (just this part, not the opposite part) and that seems to work nicely
