Lettuce Snail Slug Protection Ring Barrier Fence

Ring to put around a lettuce plant to protect it against snails. Also the lettuce seems to grow faster when the ring is around it (Only tested on 2 plants, so can be coincidence). 

I designed it to the size of a average plant I had, but then noticed it does not fit the Prusa MK3S printer, so I scaled it down (3mf file).
