Heavy duty roller blinds/jalousie wire holder

thingiverse

Unlike normal vertical or horizontal jalousie, roller blinds may apply significant load on a cord, so stock holders, especially ones who stick, may not work properly. I've got a white roller blinds, which do not pass light at all, but the drawback is that they are really heavy - stock holder is useless. This model should solve a problem. If you manage to get different type of wire, just change proper parameters at scad file.
