This is my take on a simple stake for securing things into the ground. It has a small hook and a hole to accomodate the user. There is a small flat area on the top of the stake to allow the user to hammer (carefully) the stake into the ground.
The stake has some texture to give it some purchase in the ground. Personally, I used this stake to pin the bottom edge of some chicken wire to the ground.
This stake uses roughly 10 grams of ASA printed solid. You should use a few wall loops at least for strength.
