12 Gauge Shotgun Shotshell Holder (Matchsaver) - M-Lok Compatible

Simple, single 12 gague shotshell holder to give sporting shooters that one last round to complete a stage (when you miss that last critical shot - we've all done it!).

This is a remix based on glompos21 design on Thingiverse.

I've modified the design to be M-Lok compatible, which will fit Magpul equipment and other manufacturers that use the M-Lok mounting system.

It will fit all 12 gauge shotshells, from 1 ¾" shorty shells right up to 3 ½" super magnum.

Print settings:
PETG recommended for heat and UV resistance
0.15mm layer height
40% gyroid infill minimum (but I recommend 100% rectilinear infill)
3 perimeters if you're using less than 100% infill
No supports

Two t-nuts and screws are required to mount the matchsaver. I recommend all-metal T-nuts, but 3D-printed models such as this design may work. Make sure you check the clearances on the back side of where you plan to mount the matchsaver as the 3D printed T-nuts have a much deeper profile than all-metal ones, which are designed to be low profile.
