Móc cát dạng mũi khoan (Auger sand hook)

4 pc. Sand hook shaped like an auger to drive the hook deep into the ground for stability.

0.2mm clearance to slot the pieces together.

To hold the slotted parts in place use 1.75mm filament or any pin fitting (wire, …)

Design was made to avoid supports: no supports needed

EDIT: Added a version of Side 2 with chafered rear end of thread.
