Lee APP Customizable Bullet Slider

thingiverse

Hi all, I took the good work by mainblades and extended some capability. The major change was to replace the spring pin with a 3mm hole to utilize a screw for holding the spring. You can customize your slider in OpenSCAD by modifying the bullet diameter and height. I also included an option to have a hollow body, which speeds up print time and reduces filament usage. I just finished sizing over 1200 .45 ACP bullets using my slider, and it works incredibly well. Update: A buddy of mine offered this modification (see picture #3)...instead of using a screw to hold the spring, he utilized a stiff wire bent into a loop for the spring, then pushed through and bent down on the other side. So if you don't have a screw handy, or change out the slider often, you can use stiff wire to make a loop.
