I had some leftover reflective safety tape from a different project and figured out a way to make a Geocaching container out of it.
Print one of each part. Cut a 2-inch circle of tape and attach to the outside of the lid.
I grabbed some machine screws and a couple of flat washers from Home Depot to mount the base to the sign.
If you use this for a geocache - I'd appreciate it if you share your cache page in your make. Mine is Calvin & Hobbes Cache in Illinois.
I included the Fusion file, feel free to make changes to suit your needs.
The author remixed this model.
I used the parametric model to create this container, then I added mounting holes in the base.
