This 3D‑printed beach towel clamp is designed to keep your towel firmly anchored in the sand.
The screw‑shaped lower part is twisted into the sand, while the green upper flange tightens down to hold the towel securely between the two flanges.

⚙️ How It Works

• The black conical screw penetrates the sand easily and provides strong grip.
• The towel is placed between the black lower flange and the green upper flange.
• By rotating the green knob, the towel is clamped firmly and won’t fly away.
