Drilling into concrete can be a complete pain, or in many cases impractical or impossible. This fully functional two-piece print allows anyone to hang their standard 19.1 mm (3/4″) curtain rods without any drilling whatsoever.

Invisible with grommet curtains!

The .STL file comes in two pieces purposely. First the wall mounting portion, printed base-down, arm up, for maximum strength holding to the wall. Then the curtain arm itself which looks a bit like a key.

Even more exciting is that these genuinely look and feel like curtain rod hangers.

They can be printed in any color and material, the example here was printed with Prusa brand silver PLA. Recommended colors include black, grey, silver, and white for less noticable fixtures.

When you do see them, they look like they belong

Even without grommet curtains, you can still use these mounts!

The key ingredient to avoid using screws is a strong adhesive. For this build the recommended method is to use a damage-free adhesive strip such as 3M® Command Strips® (Registered trademarks of The 3M Company). But even more critically is to strongly set that adhesive before adding weight. In this example, the pieces were assembled, ‘dry fitted’ with a curtain rod, and confirmed prior to adhesion. 4 large strips were applied to the wall mount with strong pressure held for 30 seconds, then the wall side of the strips removed, leveled and mounted in the desired location, pressed strong pressure for 45 seconds. Once applied, the mount should be left to sit without weight on it for at least 10 minutes.

When you’re ready to add the curtain rod, note that there is intentionally loose space in the ring. This is to allow easier installation. For a more snug fit, a single wrap of cable management ‘hook-and-loop’ (wrapped around the curtain rod, then slid into the ring) provides excellent stability.
