Ultra-slim nano sim carrier

thingiverse

This is a compact SIM card holder that can carry up to 16 nano-sized SIMs along with a built-in SIM tool. It has a thickness equivalent to two standard credit cards stacked together. A sliding cover securely closes the compartment containing the SIMs. Important note: This product demands extremely precise printing, preferably at a resolution of 200 microns or lower. If you encounter difficulties due to tight tolerances, consider enlarging the model by 0.5-1%. The SIM cards should slide into place with ease.
