Snap cap case, 5 round

thingiverse

A pair of simple storage cases designed to hold "snap caps" or dummy rounds are created, consisting of five round cases. The trays and lids are marked with the cartridge sizes for easy identification. Lids are secured in place using friction fit technology. Wall thicknesses measure 1mm, making a .5mm extrusion width and .25 mm layer height ideal. Update 3/22/20: New features have been added to enhance functionality: 1. A chamfer has been incorporated into the 9mm tray for improved ease of use. 2. The same feature has been applied to the 45acp tray, increasing its usability. 3. Two new models have been introduced: the 22lr and 223/556 designs. The 223/556 tray exhibits a unique design to prevent damage from sharp bullet points. Infill material is used on this particular model to enhance durability. A combination of three shells (1.5mm) and 30% infill has proven effective with various Magpul polymer 556 caps and live rounds, including those for the 223 caliber.
