AA, AAA & CR2032 Desk & Drawer Battery Organizer Caddy (24 Slots, One Piece, No Supports + OpenSCAD)

Keep every AA, AAA, and CR2032 coin-cell battery for your wireless mouse, keyboard, digital caliper, controllers, AirTags, and remotes neatly sorted in one compact, stepped caddy. Sized at 128 x 68 x 32 mm, its low 32 mm profile fits inside shallow desk drawers or sits cleanly on a desktop or workbench, printing in one solid piece with zero supports.

Includes both the ready-to-slice watertight STL (battery-dispenser-caddy.stl) and the parametric OpenSCAD source file (battery-dispenser-caddy.scad) so you can customize hole tolerances (tolerance_xy), aa_dia, aaa_dia, or well counts.
