Rock with secret compartment - for geocaching

April 16, 2025
Description
One of the things our family loves is taking hikes. We did a few Geocache walks, which were really fun.
Geocaching is an outdoor treasure-hunting activity using GPS coördinates to find a hidden container (called geocaches or caches). They are most of the time well hidden or, camouflaged as an item that belongs in the environment.
So, if you want to create your own Geocache, treasure hunt or simply want to hide something clever, you can use this rock model with a secret compartment.
The compartment is a bit less then 5 cm (2 inches) high, so if you would want to hide a key, print the model at 150%. Then the opening is about 7,5 cm x 6 cm (3 inches x 2,3 inches).
The print is supportless.
Painting advise: print in Grey (matt) (depending on what shade the other rocks are), prime, drybrush with grey and white, add matt varnish and hide away!
Be aware PLA melts, so hide it in a shady spot when using PLA.
By request I tried making my very first painting tutorial to help you with the process of making your rock look more realistic.
This video was made with one of my earlyer trials when perfecting the model, so it is smaller then the final model that was uploaded.
