I had an idea to use this cache container, but it was for an evil frog signal, so I added red eyes. I also added a profile for a TPU gasket to keep the log dry, as 3D Printed containers don't generally do well staying dry. Just drop the gasket in the bottom and drop a very little bit of glue on the very top of the thread and screw on and tighten for a minute or so. Unscrew and let dry so just in case you put a little too much glue on, you don't glue the base in. Enjoy and Cache On!!
