Hey everyone, back with another 3d model for improving your koss-blessed life.

I got myself one of those cheap headbands for putting my old porta pro drivers in. The slider unfortunately gave up quickly. (Had to bend the thing to make it fit my head in the first place! I have a small head.)

This is a really 'invisible' fix, as there is just a small difference between this and the original part. Screws are also hidden in sight. Please give it a try and let me know if this works for you. Fusion project and STEP files are also available.

Hey everyone, after my last post I have been working hard to make all the modifications people have been asking for.

Flower Grill

For all these models, there is a custom flower grill (Kramer mod) too. It improves the bass on the KSC75, from my personal experience. https://www.printables.com/model/1412670-flower-grill-for-koss-headphones-kramer-mod

Each of these mods are free, will always be free, and you are completely free to make any modifications you wish to make.

Edit: also, if anyone feels like selling kits, go ahead. The license has been chosen carefully to allow this. I will not be doing any commerce.

If you don't have a 3d printer, there are services like jlc3dp and pcbway which can print this for you at affordable prices.

Have a fine day, reddit ❤️
