Snail and slug fence

You might want to check out this improved version of the design here: https://www.thingiverse.com/thing:3216008. This simple fence makes it difficult for snails and slugs to get through - its hard surface forces them off track, and the spikes on top give them an extra barrier to overcome. Instead of a solid wall, this design features a mesh-like structure that lets sunlight reach your plants. This way, they still get what they need. The creator printed it with a brim for stability during printing. They suggest leaving the brim on afterwards and burying it in the soil for added security.
