Samsung Galaxy XR AVP Adapter

Since nobody was willing to make one, I ended up doing it myself.

This comes in to variants: An adapter to replace the the original strap with a an AVP Dual Knit Band and an adapter to reattach the original strap (which of course has to be cut off) - with optionally adding an AVP Single Knit Band as top strap.

As we all know, the comfort of the headset is horrible and while there are kits making it better, there is just no way to lie down comfortably - no matter how much stuff one adds. The original strap needs to be cut off, there is no way around it...

Since I did not want to let go of it completely (and the HMD is a bit to expensive to potential ruin it), I came up with a solution that allows to swap between two configurations:

An AVP Dual Knit Band I can use for watching movies in bed and the original strap + an added top strap when moving around. 

Quite a bit of work went into this design that isn't immediately obvious:

It took ~5 attempts to figure out the best angle for the Dual Strap - since the GXR rests on your forehead, the pressure needs to be distributed differently than on an AVP.

For the default strap attachment, the connection points for the optional top strap are as low as possible - but even then the medium strap is barely useable for my head. The small one would probably be a better choice here...

I included a picture of the cut. The adapter needs to be mounted as close to the speaker as possible - it is already quite far back compared to other headsets. As for drilling the holes: You can just use the AVP_L/AVP_R parts as a template. I used M3 screws/nuts.

I am also uploading my F3D file so people can remix the files to create their own attachments. Hopefully, we can get a sort of de-facto standard going, since you can only cut the headset once...
