S&W 929 Moonclip

thingiverse

Material: PLA 0.05 mm for resolution is likely not required. I simply wanted to be as precise as possible and work my way back from there. If you achieve success with lower resolution prints of this file, I'd love to hear about it. This print is very thin (0.035"). They are the same thickness as commercial steel moonclips, designed not to interfere with revolver operation. After printing, wrap some thin 220+ sandpaper around a Bic pen or similar in diameter and gently smooth the insides that support the neck of the cartridge. Be careful not to remove material from the narrow part of the clip that holds the cartridge in place. The cartridges should wiggle a little once in place. This is necessary for variations in neck diameters between manufacturers and also for ease of dropping in and removing the loaded moonclip from the cylinder. These are meant to be disposable. Use at your own risk. They're much easier to load/unload by hand compared to steel moonclips. This project was a collaboration between my brother and I. I sent him a scanned image of a factory steel moonclip, along with necessary dimensions. He then used that as a template layer and created the file using CAD. After only four iterations of tweaking, we got it right.
