CZ 75 magazine loader with spring assist

thingiverse

This is designed to aid the process of loading 18round cz magazines but you could download and alter dimensions to work with most any magazine. I printed with PLA. I set my perimeters/top/bottom to 4 layers w/ 100% infill with supports as needed. Dry fit before assembly to ensure the slide moves freely, your springs aren't too short(can be stretched) or too long(need shorter springs), and that the locking pin fits its hole. Sand off zits and support material leftovers to ensure smooth function. Ensure the slide and spring cavity didn't get imperfections internally that will cause binding/jamming. My locking pin's hole needed to be slightly filed for the pin to fit. If you file it too big, I imagine you could just superglue the peg into place after assembly. To assemble, stack two springs stolen from ball point pens on top of each other down into the round hole. The top spring should be most of the way into the hole. Using the end of the slide's peg, push the springs downward until the locking pin has clearance to be pushed into place. if you have any questions, feel free to figure them out for yourself, or if that doesn't work, I'll be glad to help. I'm still new to modeling so there is some cleanup that could be done but my loader operates wonderfully.
