Important!

Tiny model with tight tolerances, threads don't work it's pressure fit.

Feel free to try several materials but for me worked PETG no Supports and 0.1 Layer Height.

Design around generic/cheap 3.5mm aux jack.

Originally I wanted to design aux jack for my Fostex TxxRP but due to lack of this kind of models I decided to post generic one as well and ended up with small set/collection.

Implementation of Fostex lock is mostly a gimmick, I managed to get it to hold for the first insert but after that small squares broke off. At least it fits nicely and friction will keep it in.

Just in case you feel generous:
