Overview

This is a battery management system. Featuring Charge Status Slider, engineered Anti-Rattle Ribs and stackable bins, this parametric model keeps your cells secure and your workflow organized.

Key Features

• Charge Status Slider: A built-in sliding mechanical indicator to track Charged vs. Dead batteries.
• Anti-Rattle Ribs: Engineered flex-ribs inside the cylinders grip the batteries gently, preventing noise and tipping when drawers are opened.
• Stacking Lip: Features the "Gridfinity Extended" lip for secure vertical stacking.
• Fully Parametric: Customize for any cylindrical object using the MakerWorld Customizer.
• A1 Mini Compatible: All standard profiles fit the 180x180mm plate.

Included Profiles (Pre-Sliced)

• AA & AAA: Standard organizers with slider mechanism.
• 18650 & 21700: Deep storage for Lithium-Ion cells.
• 9V & C/D Cells: Heavy-duty variants.
• Coin Cells: Specialized trays for CR2032/CR2025.

Printing Instructions

• Nozzle: 0.4mm Standard.
• Infill: 15% Gyroid (Essential for the strength of the stacking lip).
• Walls: 3 Walls (Required for the spring-tension of the Anti-Rattle ribs).
• Material: PLA Basic, Matte, or PETG.
• Tolerance: The slider is designed with a 0.2mm clearance. Ensure your flow rate is calibrated. If the slider sticks, use a hobby knife to free it gently or increase the tolerance in the Customizer.

Bill of Materials (BOM)

• Magnets: Standard 6x2mm magnets (x4 per bin).
  Press-fit design (6.5mm holes), but a drop of CA glue is recommended for heavy loads.

Assembly Guide

1. Magnets: Press fit magnets into the base (check polarity!).
2. Slider: If you printed the separate slider version, snap the slider into the rail track before filling with batteries.
3. Loading: Insert batteries. You will feel a slight resistance as the Anti-Rattle Ribs engage—this is intentional to keep them secure.
