Geocache Padlock Riddle Box

I created a simple box that works well as a Geocache container!

The flat Lid allows for great customisations!
Here some examples where the lid was upgraded with the Geocaching Logo from AstriD3id or with a QR code that leads to a Riddle to open the padlock.
To obtain a 3D QR code object just follow this guide:

Once you have the 3D object simply merge it with the lid using any CAD software such as Windows 3D builder, Tinkercad or Fusion360.
No need to mention that the THING can be used for many other purposes!

Unfortunately, the download all option is not working well.
Please download the files one by one in the thing Files section.
