Arrow Roller Blind Cord Connectors or Ends

thingiverse

These roller blind ends can be used to either terminate the ends of a cut or broken roller blind chain, or to join a cord together again. Simply pick which style of arrow you want, then print two of it (you need to print two halves per arrow). Then join the two halves together using a couple of ø3mm x 7.5mm screws. This connector is designed for roller blinds consisting of ø4.5mm beads, spaced at ~12.15mm intervals along ø1.6mm cord. The square holes for the beads are 5mm cubes, and cord hole through the centre is 2.5mm wide x 2mm deep. I designed the arrows to screw together, rather than gluing or clipping together, to make them easily removable and very strong. I picked the ø3mm screws, as I have a LOT of them, as a result of disassembling various electrical items (printers, radios, microwaves, etc), which tend to use a lot of this type of screw. If simply terminating the cords, rather than joining a cord together again, the arrows can be used to show which direction the blinds will go if you pull on that end of the cord. the arrows can be installed pointing either direction, and can be installed at the end of the cord or part way along. They're versatile!
