Blinds / Shades Pull Cord Grip & Extension

thingiverse

I needed an aesthetically pleasing, comfortable to use, strong pull for the cord to my mini-blind shades. This raindrop-shaped pull is easy to grip and the two halves seamlessly screw together to create an exceptionally strong link. What separates this from other pulls I found on Thingiverse is that this can function as a coupler to extend the reach of your cord. The two halves simply screw together in a very secure manner. When assembled the seam is nearly impossible to see. As an added bonus, the cord knots are entirely hidden inside the interior cavity. I used Autodesk Inventor to design the pull, along with the excellent free add-on called threadModeler by coolOrange to create a physical model of the easily printable M12x1.5 threads. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: No Supports: No Resolution: .2mm Infill: 50% Notes: Shells are more important than infill in this design due to the strength requirement at the screw threads. I used 3 shells to great success.
