Time Capsule – 3D Printable Sealed Storage

This 3D-printed time capsule is designed to safely store small objects for long periods—perfect for preserving memories or surprises for the future.

It comes in various sizes (from Extra Small to Extra Extra Large) and, when printed in PETG with the right settings, it's water-resistant and built to last for years.

The model includes two parts: the box and the lid.
Start by printing the lid first. Then begin printing the box. Inside the box, there’s a small marking—pause the print when that layer is fully visible (If you are using the 3MF format, the pause layer is already marked). At this point, insert your items, place the lid inside (it also functions as a support for the upper layers), and resume printing to seal the capsule completely.

You can add any text you wish on top of the box using your slicer.

Simple, fan, and perfect for long-term memories storage.
