First design to upload and first entry in a competition! I hope you like it and please give me feedback. A picture of the full printed model will be uploaded shortly.

This is a sand screw anchoring system for your beach towel or mat to keep it from blowing away in the breeze. Print files are the anchor and wrench in one, plus the anchor separately for convenience of slicing the additional anchors and printing.

Printing in PETG for strength and durability, the test model was used in hard ground instead of beach sand and powered in easily.

Easily scalable for your preference, 80% size scale works well for the hard ground where the 100% will give a better hold in the sand.
