If you need compact and lightweight box for your precious democracy this is perfect thing for you. I designed this to have no excess weight so it has no compartments - bullets are held by friction, and it holds 30 rounds so you can easily count how many magazines you can load.
To fill this just grab tray in our hand and tilt it to about 30 degrees and place 4 rounds in bottom corners (see in the pictures). Later just add more until there's one place left and press the last round in to lock everything up.
To change how strong everything hold up just scale it down or up a little bit like 0,1% or 0,2%. For me at 100% it holds loosely.
Honeycomb finish was achieved by setting bottom and top layers to 0 and adding honeycomb infill.
Warning!!! Check your local gun laws because some require primers to be covered.
I've also designed simple cover that fits over everything and secures bullet from falling out, but it misses good and secure lock (suggestions are welcome)
