About this 3D model

Use this to secure your beach towel in the sand on a windy day. Thread your towel through the opening the arrow points to, then pull it up and through to catch it in the V. Bury the whole thing and your towel should be secure. I made one of these yesterday, but then got to thinking that no matter how long the spike is, it's probably going to fly out on a windy day. Then I got to thinking about how you could better anchor something in the sand and came up with this.
