The simple slug trap is designed to easily capture slugs in your garden to reduce damage to plants. 

I have printed these in pla and petg without issue. Pla may warp in hotter regions.

Easy print , <50g of filament, <2hrs. print time

Just slice and print

Dig a shallow hole in the ground where you want to place the container. 

Place the container in the hole.

Fill the trap container halfway with beer or whatever bait you prefer. Beer seems to work great.

Replace the top cover to protect the trap from dirt and rain.

Check the trap regularly. When the trap is filled with slugs, rinse it with water and put it back in the previous hole and add new bait.
