usb desk organizer

USB Desk Organizer (Learning Project) This is a USB desk organizer I designed while learning 3D modeling in Fusion 360. The goal was to build something functional while figuring out real-world tolerances, fitment, and basic design workflow. 🔧 Versions V1 First working prototype Functional, but USB-A ports were too tight (very strong press-fit) V2 (Current) Adjusted USB-A tolerances for proper fit Added additional ports Added a tray for USB caps and small accessories Improved overall usability and layout 📏 Dimensions (Critical Fit Info) USB-A Ports 12.3 mm × 4.8 mm 14 mm depth 0.3 mm corner radius These were tuned using test prints in 0.1 mm increments to get a snug fit without excessive force. USB-C Ports Face opening: 8.5 mm × 2.7 mm Corner radius: 1.35 mm 14 mm total depth Rear cavity: ~ 9.2 mm × 4.2 mm USB-C was less sensitive but still benefits from slight clearance depending on your printer. 🧪 USB Size Test File I included a file called usb_size_finer (yes, typo — it was supposed to say "finder") . This file contains all the USB-A size variations tested (in 0.1 mm increments) so you can quickly determine what fits best for your printer and filament. Each slot represents a different size A 1 mm hole marks the smallest USB-A size You can print this first to dial in your tolerances before printing the full organizer 👉 V2 uses the middle size from this test set (12.3 × 4.8 mm) 🖨️ Print Settings Layer height: 0.16 mm Infill pattern: Rectilinear Infill density: 20% Wall loops: 2 Supports: Not required 🧵 Printer & Material Printed on a FlashForge Adventure 5M Pro using: ELEGOO PLA (1.75 mm) Polymaker PLA (1.75 mm) Both materials produced similar results, but fitment may vary slightly depending on your printer calibration and filament. 💡 Notes This was a learning project, so it's not fully optimized Fit may vary depending on printer calibration and material If ports are too tight/loose, adjust dimensions by ±0.1 mm Adding a small chamfer to the front edges can improve insertion feel 🚀 Future Improvements Snap-fit or retention features for connectors Parametric version for easier scaling and spacing Cable management improvements Port labeling or embossed text 🧠 Feedback I’m still learning, so any feedback is appreciated. Let me know what could be improved or what additional info would help! (And yes I used chatgpt to write this description, that is the only thing AI helped)
