This is a 20 Round 7.62x54R ammo box. It has a locking sliding cover. I like to slide the cover back to reveal 2 rounds and dump them out in 2 round increments. It was designed to have the bullet side facing down because of the rim. It is an easy print and requires no support. You can adjust the colors easily in the Bambu slicer. The bullet color, brass, and text are easily changed in the slicer. The text is also user editable, so you can customize it.   Please let me know if you have issues. I do not use this round and this one was user requested.

Check out my other ammo boxes for similar designs. If you are looking for another caliber, just let me know via a DM.  I am in the process of updating all the designs to the Gen 3 style, so it might take me a bit to get to a custom odd caliber. I go in order of most popular first.

Updated Design! - Gen 3

• Snap in Side Labels that are customizable - The text, color, and frame color can all be customized by the user. 
• Stackable - Chamfer on bottom and mating feature on cover.
• Customizable Text on Lid
• Improved Robustness - Wall thickness increased
• Moved snap lock feature from start to end of the cover groove. This will improve the issue a few folks had with the the seam delaminating between layers. 
• Simplified Geometry

Assembly

1. Snap in side labels - Hook one of snap features of the label and slide your finger across to engage the other snap feature. 
2. Snap in Round divider Tray  - It you need to remove this just use a pencil and gently pry it to disengage the snap feature.
3. Slide Cover on - The first few snaps will be a little firm, but it will loosen after a few and it sits for couple days.
