.30-30 pocket ammo case with sliding lid. Holds 6 rounds. I tried to make the case to use minimal filament with minimal print time.

If the tray doesn't fit snug: Place a drop of superglue on each post and then press the tray onto the posts. Let the glue fully dry and before placing ammo inside, or before sliding the lid on. This is to prevent any superglue residue or “bloom” from getting on your ammo and lid.

When printing the tray that you stick the rounds into you may have to adjust the X-Y hole compensation in your slicer, depending on how well your printer is calibrated.
