Description

Hello folks,

I've been using the Sturdy Meta Quest 3 mount (Link) for some time and it's an amazing design! However, some things bothered me:

The "spring" mechanism didn't provide enough pressure to keep the headphones firmly on the ears.
The sliding mechanism was not smooth, often skipping snapping points.
There is a risk of the headphone adapter breaking, but it required reprinting the entire arm.
The sliding mechanism had limited adjustment distance.
The mount was loose on the Quest's strap, necessitating additional tape for a secure fit.

To address these problems, I designed my own variant to enhance the experience, making it as seamless and smooth as possible:

A rubber band mechanism ensures consistent ear pressure and snaps back to the idle position.
Smooth sliding mechanism for easy positional adjustments.
Modular headphone adapter, allowing for easy replacement in case of failure.
The strap mount has been tightened for a secure fit without extra tinkering.

The .3mf file includes everything needed for two sets.

Additional Required Parts:

2x M3x14mm rounded head screws.
8x M2x6mm hex socket head bolts.
Small rubber bands, like those "Rainbow Loom" bands. Adjust the amount and size according to your preferred pressure force.
Drivers from the Koss KSC75 (recommended) or Koss Porta Pro

Building Instructions:

Simply snap everything together and insert the screws into the corresponding holes. The process is quite straightforward. Refer to the images as a guide. I've also made a video to demonstrate the build process and make it easier for everyone. You can find it here:

Printing Instructions:

Default settings. Use tree support for the clips.
I've used PETG but anything like PLA is fine.

I have the elite strap and thus it's made for that. For other straps some editing to the clip might be necessary.

If you have any feedback, let me now!

Have a great day!

Absolutely love this idea. I went ahead and remixed it to work with my BoboVR S3 strap! Thanks for the upload!

Thanks for remixing for S3. I'm copying the same comment I made for the parent model: I didn't have M- type screws and none were sold in those small sizes in my local hardware store. Instead I used some small wood screws I had on hand: I was able to use #4 x 1/2 inch wood screws in the smaller holes for holding rubber bands. Smaller diameter screws would be better since it was a very tight fit, but it worked out. I didn't have to bore out the hole, but it did take some patience. I used a #5 x 5/8" wood screw for the two 'hinge' screws instead of M3x14mm. One of them is flush, but the other for some reason has its 'point' slightly poking out. I might file it down the edge a touch to make sure it doesn't scratch me and screw it back in. I got those tiny rubber bands at Walmart for about $3. P.S. Koss Porta Pro driver = SportaPro Driver = KCS35 Driver; these drivers are all exactly the same, but the Sportapro are usually much cheaper. Just a note to others who want that driver. The KCS75 is a different driver, but it is even cheaper than the Sportapro so that may be the cheapest option since the headband/clips don't matter to you. A lot of online reviews say they acoustically are similar, with slight differences. I kind of doubt it will matter too much to most people doing this mod, so I would suggest you buy any of those that is cheapest for you, whether new or open box to shave off a few more bucks.

Absolutely fantastic guide and video. Thanks much for this. I'm using @porksnout 's modification for the S3 but your video really helped me make sure I understood what I was putting together and their orientations.

I'll try to remember to post a picture in case others have trouble sourcing M screws of those sizes without overpaying for shipping on a big pack when they only need a few. P.S.
