The model is a multifunctional sand anchor onto which various attachments can be screwed. With the files herring base and a herring top, it becomes a tent peg. Another herring top can be used to attach a towel. The basket can also be screwed on to store important items.

Fun fact: I used the middle threads of the Multiboard system. This means that the sand anchor is multiboard compatible (no idea who would benefit from this).
