Thanks for downloading!
We'd love to hear from you if the print was successful.

Stratocaster's original post on headfi linked below
That is the original post that inspired this design, describes the goals of the project and introduced me to headphone modding,
However going through the effort of making or buying wood cups, headband, gimbals and earpads adds so much to the build that you may as well use more expensive Sennheiser drivers instead.
So I decided to design a set of cups that would be simpler and cheaper to make. The earpads and headband pad in the pictures are nice additions but not required as it is light enough to not put much pressure on the top of your head and the clip holds the KCS75 out of the cups enough that the padding that comes with them can be used.
Close the holes in the cup with tape from the inside and fill the cups with loose cotton wool to adjust the sound.
Materials and methods
3d print 2 sets of parts and glue the tabs to the center post inside the cup.
Test fit the Kcs-75's then form a headband from the wire and slip it through both cups.
slide the end pieced onto the ends of the wire.
Issues are used to track todos, bugs or requests. To get started, you could create an issue.
Some tips for other n00bs like me:
- the holes for the headband wire are 3mm. In my print they came out slightly smaller. I have 3.15mm wire so I ran a drillbit through by hand to make the holes slightly larger, and it works great.
- the wire you're looking for to make the headband is often called music wire or piano wire. Basically it's spring steel, so it won't deform as soon as you put the headphones on
- those two little pieces in the print are meant to be glued into the centre of the cup and that's what the drivers clip into. Yeah, it's obvious once you know but it took me longer than it should've to figure it out.
Nice job! What pads are you using on the headphones pictured?
