I recently borrowed a microSD card from my friend Paul and decided to send it back to him per mail. But placing the card directly in an envelope seemed a bit risky, since it is thin and small it might get damaged or lost. Therefore I decided to create an enclosure to put the card in during transport.
This model is a remix of the Micro SD case by Halldor Gunnarsson:
Printed with PLA and 0.1mm layer thickness
