The file 'Springfield Hellcat 9mm Magazine Speed Loader 3D Printer Model' is (stl) file type, size is 119.5KB.
Created just to see if I could. One of my first design projects, feel pretty good about the outcome except for the ridges at each of the bottom corners. If you don't like it, you can remake it to your liking. I couldn't (and still can't) figure out how to round out the lip at the bottom. Designed in TinkerCad, sliced in Cura, printed on Creality Ender 3 Pro with 1.75mm PLA filament.
Printing: Nothing fancy. 20% quality, no supports, no modifications to default Cura settings. I DID however print this upside down, and though it looks like it won't stick to the print bed, mine did just fine without any supports. Slice however you wish.
Also created a similar model for the H&K VP9/VP9SK.
