Snap cap case, 5 round

Just a pair of simple 5 round cases for storage of "snap caps" or dummy rounds. The trays and lids are marked with the cartridge sizes. Lids are friction fit. Wall thicknesses are 1mm, so .5mm extrusion width and .25 mm layer height is perfect.

Update 3.22.20:
1. added chamfer to 9mm tray.
2. added chamfer to 45acp tray.
3. added 22lr and 223/556 models

223/556 tray is somewhat different to prevent sharp bullet point from damaging thin base of tray so some infill is used on that one. I used 3 shells (1.5mm) and 30% infill. works good with both Magpul polymer 556 caps and various 223 live rounds. (I didn't have any 223 or alloy 556 snap caps.)
