Side-loading single shell Match saver

thingiverse

Single shell 12 guage match saver for mounting with double-sided tape (no holes for bolts). Designed to be mounted on the right side of the gun, however can easily be mirrored when slicing for mounting on the left side. The curved bottom model fits the curve on the handguard of a Winchester SX4 perfectly, and may fit other handguards. The flat bottom model will stick best to a more flat sided handguard but can also be mounted on handguards with small curves (it also fits the Winchester SX4 nicely). The lowered cut-out makes it easier to quickly push out the shell without having your finger get caught on the match saver. When printed with PLA and a wall thickness of 1.2 mm, the springiness of PLA makes this design hold on to a slim 6 shot shell perfectly, however, is a bit too tight for larger shot sizes. Decreasing the wall thickness to 0.8 mm makes the match saver capable for use with bulgy shells up to at least shot size 2, however, will decrease the grip on the smaller shot sizes.
