Window blind cord pull circle
thingiverse
I tried fixing my window blind but couldn't find the part I needed. So I made this round piece for the end of the cord myself. The other item shown is the roller blind pull string fastener by GalFisk. It was published on April 21, 2017 and can be found at www.thingiverse.com/thing:2256170. This one works well too, you may need to ream out the hole a bit depending on your cord's thickness. You can use this for commercial purposes without any cost.
