I recommend printing this with PETG, ASA or ABS if it is going to be exposed to the sun. Works well with the layer height of 0.3 mm and 10% infill. No supports needed.
Assembly
For this snail trap, you only have to assemble 3 parts. First you have to put the net into the cup then you pour in the mixture of approximately 100 ml of beer (half cup) and 2 tablespoons of sugar. Put the cap on so the mixture will be protected from the water. Then bury the trap into the soil about 3 cm deep.
After a few days you just have to remove the cap and collect the snails and slugs with the net and just toss them into the compost.
