Sign post geocache

Spotting a new spot i needed a new type of geocache to fill it

this design immediately got stuck in my head, once i looked over the area.

its designed to fit inside a standard British council sign pole, the outside diameter of the lid is 76mm and the inside tube is 65mm

inside there is a recessed cavity for the log and small swappables, there is also slopped supports for the ceiling - these double up as ramps so that if its being difficult to get something out you can simply invert it and it should slide out easily

added photos of the cache in situ so you can see what it looks like
