SD + microSD Card Desk Holder (4 SD / 8 microSD)

Compact two-tier desk holder for memory cards. The tall back tier holds 4 full-size SD cards, the low front tier holds 8 microSD cards in 2 columns. Slots are tilted back 10 degrees so the labels stay readable and cards are easy to pull out.

Size: 36 x 56 x 19 mm.

Print settings (FDM): PLA or PETG, 0.2 mm layers, 3 walls, 15-20% infill, no supports needed. Print flat on the base as oriented. Slot clearances are sized for a 0.4 mm nozzle; if cards are too tight, scale X/Y up 1-2% or edit sd_t / msd_t in the SCAD file.

Parametric: designed in OpenSCAD. Change n_sd, n_msd_rows and pitch values to make it bigger or smaller.
