What in tarnation is a LeadBed?

LeadBed is a parametrically-designed, Gridfinity-compatible*, stackable, multi-caliber ammo box system.

The goals of this project were to create an ammo box solution that:

• covers all of your calibers in one design
• covers all needed box sizes in one design
• takes up as minimal filament / space as possible
• is rigid and secure enough to throw in a range bag
• stacks and arranges cleanly
• printable without supports
• caliber is clear from all viewing angles
• fully 3D printed - no screws, nuts, or magnets needed
• Gridfinity-compatible*

Ok Mr. Fancy Pants, how do I make this thing?

1. Download and extract zip file for your desired caliber

2. Subfolders are organized by grid dimensions. (If you have crippling option paralysis, my favorite is 4x2)

3. Using settings listed below, print one of each: Box.stl, Lid.stl, Holder.stl

4. Insert holder into box, keeping holder parallel to floor, until all four corners rest on box support beams

5. Slide lid fully into slot at top of box

6. Done. Fill with your ammo of choice and enjoy your secure pew pew storage.

Hold on there, partner - why the asterisks by "Gridfinity-compatible"?

All Gridfinity-compatible components in this model are designed by hand from scratch, and are not the work of Zack Freedman nor subject to licensure. The base plates are to spec and should be compatible with any other prints. The stackable lid dimensions are to spec, but due to lid design, only encompass one large grid rectangle. 4 squares will fit on top of one 4x1, but 1 square would slide along its length. In an effort to save print time and filament/improve rigidity, height is not standardized to increments of 7mm.
If there is interest in a full-fledged version, leave a comment and I can do so in future iterations.
