I did a sketch for Make Anything's Tippi Tree competition, and I liked the concept so much I decided to model a proper version. (without the Tippi Tree)
This is the sword in the stone, from the classic fairy tale. It's one of my favorite childhood stories and I hope I was able to do it justice.
If you are printing this in resin, you shouln't need any supports.
For FDM this might be a bit more difficult. You can probably print this support free if your printer handles overhangs and bridges well. I would recommend using small layer heights, and tree supports.
