camera battery tray 3d model

Create a standalone removable organizer tray insert for a rugged hard protective case, optimized for precise FDM 3D printing and realistic industrial CAD modeling. The tray must fit inside a compact waterproof equipment case and contain storage compartments specifically designed for Sony NP-FZ100 camera batteries and 6 SD cards. Design only the tray insert, no outer box, no lid, no hinges, no latch, no case body. Tray style should match professional camera equipment organizers with clean geometric surfaces, compact spacing, and efficient use of volume. Use a rigid industrial appearance similar to injection-molded or precision 3D-printed equipment trays. Include slightly rounded corners and clean chamfer transitions for strength and usability. Tray layout: • Two large battery compartments positioned left and right • Central SD card holder section between battery compartments • Six horizontal SD card slots stacked vertically • Compact layout with minimal unused space • Symmetrical
