This is a scaled up 'Nano Geocache' with a diameter of just under 200 mm and total height of around 200 mm. There are threads on both the lid and body.

The Lid does not screw down all the way, this is to allow an o-ring to be fitted, I modified an o ring from Amazon, https://www.amazon.co.uk/gp/product/B07DGBF78T/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1,

The Body was printed with no supports with the solid base touching the build plate.
