Bigscreen Beyond | SANE DIY Custom Head Strap

After being disappointed and mad at the default soft strap the beyond ships with, I decided to do it myself, in the way that I would if I was in charge of designing the big screen strap myself. Since I think weight is the BSB's greatest strength, the strap should strive to maintain as low weight as possible while giving the best audio quality possible. Since I came from an Index I did not want to compromise on that. I also think rigid or semi rigid straps are objectively more comfortable in VR headsets.

3D PRINTED PARTS:

All of these need to be printed using my settings for layer height, orientation, supports etc.
Therefore you need to use orca slicer or an orca derived slicer that can open the 3mf files I am posting and import it all correctly.

Nozzle: 0.4mm
Material: Your best PLA

Make sure the parts look like the pics below in the slicer in terms of layer height and supports.
0.08mm layer height in the blue areas is !!IMPORTANT!!

Print Settings:

I recommend copying especially the overhang speed settings because without this I couldn't get good results, but this all depends on how strong the cooling is on your printer, on my standard Anykubic bed slinger I needed to go this low.

THIRD PARTY PARTS:

Moondrop Old Fashioned Headphones:

MOONDROP OLD FASHIONED USB-C Cable Version

Elastic Velcro Straps:
Elastic Hook Loop Nylon Bands 30mm width

Rubber Back Head Support:

Headband Cushion Head Strap for Meta Quest 3

Assembling it all together is pretty straightforward, the screw holds the headphone hooks in place, the headphone cable goes in the groove on the model etc. The only place that one might struggle is attaching the Moondrop headphones to the hooks, but for that I say just watch the video on the remixed hooks I used: https://youtu.be/7ZdojztMjvg?t=91

Stuff I would welcome help with:
Make the screw mechanism more reliable and the thread better suited for 3d printing.
Make the headphone hook adjustable outwards/inwards without loosing the ability to lock it in.
Or alternatively, create different hook shapes for different head sizes.
Tune the tolerances on the headset attachment geometry to make it more solid and long lasting.
