Gridfinity Battery Organizer (Parametric)

Organize your batteries exactly the way you want with this Fully Parametric Gridfinity Battery Holder!

Instead of being stuck with pre-made sizes, this OpenSCAD model automatically calculates the maximum number of batteries that can fit inside your chosen Gridfinity base dimensions. Simply select your battery type, choose how many Gridfinity blocks wide and deep you want the bin to be, and the code handles the rest—perfectly centering the layout and ensuring standard minimum wall thicknesses.

Key Features:

Auto-Layout: Just pick your Gridfinity X, Y, and Z dimensions. The model does the math to fit as many batteries as possible without breaking the walls.
Multiple Battery Types: Pre-configured for AA, AAA, C, D, and 9V batteries.
Custom Sizes: Have a weird battery or cylindrical tool? Use the "Custom" option to type in your own diameter.
Smart Safety Limits: Built-in math prevents the battery holes from accidentally punching through the bottom of the bin, guaranteeing a solid floor no matter what depth you choose.
Easy-Grab Chamfers: Cylindrical battery slots feature a 1mm top chamfer so you can easily grab and remove batteries.
Optional Magnet Holes: Toggle standard 6x2mm Gridfinity magnet holes on or off in the customizer with a single click.
