Cable release socket design

Cable release socket design

Print it (preferably in a way that the wider hole is at the bottom). Force gently - preferably the new Chinese manufactured (as they are a bit thinner) - cable release starting from the wider entry, all the way through, just until you hit the other side. Gently unscrew. Blow out the excess material. Enjoy.

Dimensions: 0.35mm in height, 0.28/0.38mm diameter at the ends.
