Wall-mounted SD card and battery holder
Camera batteries and SD cards pile up fast, and a wall-mounted holder keeps charged batteries and empty cards separate from used ones. The holder has a row of six battery slots 40 x 20 mm sized for common mirrorless packs, plus twelve SD slots 25 x 3 mm angled at 10 degrees so the labels face you. A 2 mm back plate with two 4 mm keyhole hangers, 1.5 mm dividers and 0.4 mm clearance on each slot make everything slide in without rattling.
SpeakCAD lets you enter your actual battery dimensions, whether NP-FZ100 or LP-E6, plus the number of cards you own, and generates a holder sized to them. Add microSD slots or a charger cable clip in the chat and preview the whole thing free before downloading.
