SD card and USB stick desktop caddy
A compact block with angled slots that hold SD cards, microSD adapters and USB flash drives upright so the labels face you. Slots for full-size SD cards are 25 mm wide by 2.8 mm thick, microSD pockets are 11.5 by 1.2 mm, and USB slots are 13 by 5 mm; a 0.3 mm clearance keeps insertion firm without scratching contacts. A 15 degree lean lets cards stand without falling, and a solid 8 mm base stops the caddy tipping.
Generic caddies never match the mix of media you own. In SpeakCAD you say how many of each card type you carry and the chat produces a caddy with exactly those pockets. Preview it in the browser for free, adjust slot depth or spacing by replying, and download the STL only when the layout is right.
