I created this to make it easier to mow and trim around my very small, sad, and slug-infested rhubarb. I was going to make one out of wood, but I realized that 3D printing would be easier.

It's designed to be filled with something like mulch to prevent weeds from growing. I used bark, which drains quickly, so hopefully it won't cause rotting.

The model is sized to fit the maximum bed size of a K1 max. I think you should be able to scale it if you want something smaller or larger.

I printed mine in PLA, because that's what was in my printer. PLA and PETG are probably reasonable material choices for this, you'll want it to be fairly UV stable for obvious reasons. ASA is apparently very UV stable.

A layer height of 0.2mm, or greater, is appropriate for this print, and you won't need much infill.
