I created a series of kissed, married, and killed tombstones. There multicolor options, as well as, single color models. I provided two lengths of stakes and personally used the shorter and it was fine but your results may vary depending on the soil you drive these into. Finally, these are taller, and wider, than most printers support. I printed these with a prusa xl.
I recommend printing the stakes with 5 walls.

The author marked this model as their own original creation.
