Safety marker (ECI) for Ruger GP100 and S&W 686 (.357)

thingiverse

Safety marker that fits Ruger GP100 and Smith & Wesson 686 revolvers with caliber .357 Magnum. This remix features smaller/lower chamber plugs and a slightly smaller/lower outside marker compared to the original design. Available in two versions, one for Ruger and another for S&W (and clones), with the only difference being the Ruger logo on the outside marker area. When printing, ensure that solid layers are defined at least six at the bottom, so the first one or two layers of the chamber plugs attach smoothly to the 1 mm thick bottom plate. If not, the plugs may break off easily.
