Customisable Pulley
thingiverse
This is an OpenSCAD file for generating a pulley that will fit your blinds pull chain. You simply need to take 2 measurements from your chain which is the bead diameter and bead spacing in millimetres. The attached STL is the one I used which is suitable for 3mm beads with 1mm spacing. Hope others find this useful.
