This geocache is 3D printed in PLA in the shape of a snail shell. It contains a small magnet integrated into the base of the shell, allowing it to be discreetly attached to a metal surface. On the top, an NFC chip is integrated. It can be programmed to store information, such as a link to a web page, a video, a puzzle, or instructions for the geocache. The NFC chip can be programmed using the NFC Tools app on Android or iPhone.

In the 3MF file, the print pauses required to insert the magnet and the NFC chip are already configured. You simply need to follow the pauses during printing, insert the components, and then resume the print.

According to the drawing, the geocache includes a PLA snail shell, a PLA cap, a 6 × 2 mm magnet, and a 25 × 0.8 mm NFC chip.
