Holds 6 .270 caliber rounds to the side of a rifle. It is attached with 2 small zip ties. The holes for the zip ties are on the backside. Holds firm, doesn't wobble or rattle when shooting. It's currently mounted on my Remington R700 with a Bushnell scope.
I made this because I normally place my shells in my pocket, they either poke me or jingle around.

Print time on my printrbot was just under 2 hours. That will vary based on your configurations. There is also some very minor bridging if you print it the way I have it orientated. Be sure to have support material turned on if you do lay it on its side to print.
