I tried a bunch of different light seal sizes and couldn't find one that made the AVP comfortable on my face. The clip on adapters that other people have released didn't look great and weren't perfect for me so I designed my own. This adapter is unique in that slips over the AVP audio straps from the front rather than clipping on from the sides (you'll have to remove the straps with a SIM ejector to install the adapter).
The second strap sits at a -5 degree angle (i.e. 5 degrees towards the back of my head), which I found to be most comfortable for me but I'm including the 3D printing files here if anyone wants to play around with the design.
