This key fob holds 2 Micro SD & 1 SD Card in a very small package, with a secure twist lock.

Just place your cards in two layers, then drop the top on and twist to align the attachment hole, looks like a standard RFID key fob, but securely holds your data!

This is designed for PLA, and prints fine with a 0.4mm nozzle, though a layer height of 0.1mm is recommended to capture the detail in the latches.

Uses very little filament and prints very quickly, even at 0.1mm layer height

First layer - 2 Micro SD

Second layer - 1 SD Card

Top goes on at an angle

Twist to close

Lobster clip to lock and complete the illusion!
