dig small hole, add beer, place lid over the top, and watch drunk snails meet their doom!

parametric modelling in openscad.
Print one of each part, add beer, done.

Originally started to replace the sun damaged lid of our existing snail traps, once I had finished the lid, was a simple task to add the base as well. now here for all to save their veggie gardens from snails where ducks are not present.

I have not yet test printed the base, but this will not be an issue, its as straightforward as it gets.
