in case you need two-sided eyelets, i add a extra eyelet (pulley_eyelet) which is easily mounted to pin.
you also need print the modified pin (pulley-pin-mod) with 1.65mm longer.
if this eyelet is too loose, you can increase the height of pulley_eyelet stl a little (e.g 0.2mm) in your slicer.
get other files from the original, also follow the print tips there.
The author remixed this model.
add a extra eyelet for convenience
