USB, SD & MicroSD 3D Desk Hub - Clean design

Keep your desk tidy and your media organized with this 3D-printable USB, SD & MicroSD Desk Hub — a compact, stylish organizer that holds USB adapters, full-size SD cards, and microSD cards, with an extra front tray for small items like keys, cables, or adapters.

This model is optimized for 3D printing and for real-world usability:

• Designed for common adapters — USB-A adapters, SD cards, and microSD adapters fit snugly while remaining easy to remove.
• Two-tone lettering option — recessed letters allow for easy color fills or filament swaps for a premium look.
• Stable desk footprint — low profile with a slight lip at the base so the hub doesn’t slide easily.
• Functional front tray — space for small items: screws, keys, dongles or a pen.

Perfect use cases:

• Home office organization
• Maker bench / electronics hobbyists
• Studio / photo memory management
• Gift for tech-savvy friends

✅ Files included

• Main hub body (multi-part or single STL depending on your preference)
• Optional printable inlays for two-color lettering

🖨️ Recommended print settings (start here)

• Perimeters / Walls: 3–4
• Infill: 12–25% (25% if you want a stiffer tray)
• Supports: Minimal / none — design is optimized for few or no supports; enable supports only for your printer’s overhang tolerance
• Nozzle: 0.4 mm recommended
• Bed temp: 60°C (PLA) / 70–80°C (PETG)
• Print speed: 40–60 mm/s for best surface finish
• Tolerance: If your printer tends to be tight, add +0.2 mm scale on card/USB slots or increase X/Y by 0.5–1% to ensure smooth insertion/removal

🔧 Print tips & multi-color options

• For two-color lettering, print the lettering in a contrasting filament and glue into the recessed cavities, or use pause-at-layer / color-swap for single-extruder printers.
• Light sanding and a small dab of glue will keep inlays flush and clean.
• If cards are a tight fit, test-print a single slot at 100% scale first and adjust in your slicer using uniform scale or X/Y compensation.
