Handheld Cartridges Storage (GameBoy, Color, Advance, DS, 3DS, Switch, GameGear, PSP, Vita)

Meet the "Handheld Cartridges Storage"👋 ============================== I have a lot of loose retro games for GameBoy and GameGear and some other consoles. I looked online for storage solutions for a while, but was never satisfied. Printed racks I downloaded pinched the carts too hard, leaving faint marks. I also wanted a closed box, to protect cartridges from UV light and yellowing, but also sometimes for carrying. I decided to create my own solution while learning CAD, and publish it for all game collectors. I hope you enjoy them. 🙇 Updates! 🆕 ========= **2026-04-14** - v3-rev05 - Corrected minor errors on "ds-guitar-grip", "ds3ds-bigboy". Corrected a small but impactful error on "ds3ds-pico" that could make the box difficult to open. **2026-03-24** - v3-rev04 - Added "ds-guitar-grip", "gba-bigboy-withcase", "gbgbc-bigboy-withcase", "gg-bigboy", "gg-bigboy-withcase". Reduced infill to 16%. Removed STL files, keeping only 3MF, to reduce release size. **2025-12-26** - v3-rev03
