hey. can't believe that at 2016, I am still using 2 pairs of koss the plug I have modded years ago. The can finally gave out completely and is breaking the cord badly. So I made this can to replace it. Just a simple cylinder to make sure it is easy to print.

The ear plug is made for ER5 plug.

Not sure how many people had been modding this super cheap ear phone.. Mine had been through 5 cord replace, and it is somehow still kicking after 10 years.

maybe this can still help someone!
