Window Curtain Cord / Cable Tensioner

This 3D model is a practical and minimal curtain cord / cable tensioner designed for window curtains.

The model consists of two separate parts:

• Main hollow body – designed to be filled with weight (sand, small stones, metal pellets, or any preferred material) to keep the curtain cord properly tensioned.
• Snap-fit cap – securely closes the body and locks the filling material inside without the need for glue.

Thanks to its hollow design, you can easily adjust the weight depending on your needs, making it suitable for different curtain types and window sizes.

Features

• Simple and functional design
• Adjustable weight by custom filling
• Secure snap-fit closure
• Easy and fast to print

Ideal for replacing broken tensioners or creating a custom solution for your window curtains.
