9mm Luger Dummy Parametric

thingiverse

Parametric 9x19mm Snap Caps / Dummy Rounds. Ammo is expensive and dry practice is important. I had some problems getting other models to work out of the box. My printer tolerances aren't perfect for every filament. I tried scaling it in the slicer but noticed that the proportions were off. Some printed dummys even got stuck in the chamber of my G19 and I had to remove them with a corkscrew - so be careful and double check before you load them into your mags. Making it parametric lets you dial in the exact measures in Fusion 360. Just print the stl (which comes with the official dimensions) and use a caliper to see how much you are off. The parameters only work for the diameter of the round, as the length is not that important (you could simply scale the z axis in your slicer).
