Curtain Pull Tensioner

thingiverse

Curtain pulls perform best when they are meticulously matched to the curtain and the window. Curtain pulls are frequently made cheaply and poorly designed, often comprising numerous parts and breaking easily due to their intended versatility in adjusting positions and heights. In my case, I had a kitchen curtain on a three-section window that utilized a simple (and inexpensive) plastic piece to secure the bottom of the string. The plastic piece was designed to be screwed into the window frame; however, with the three-section window configuration, the middle section lacked a suitable point for screwing in the plastic piece, leaving the pull string dangling. I created a custom curtain pull tensioner that screws into the windowsill and keeps the pull string under gentle tension using a spring readily available at most hardware stores or online. The tensioner can be tailored to the height of the curtain pull by modifying the OpenSCAD source file. The practicality of this design remains uncertain, but it appears as though others may find it useful as a general-purpose household item. If you decide to build one, I'd appreciate knowing about your experience!
