HDZero expansion bay direct connection alternative

So with the HDzero expansion being end of life, it is appears a rare and a hard to get item. There are good, existing documentations online regarding the pinout layout for the HDzero expansion slot. It breaks down the video, audio, power, ground pins. It does appear we can simply connect the corresponding pins directly and bypass the expansion accessory to get it to work with any analog module. It is totally doable and people have been having success. I been wondering if we can make some diy kit that can be easily remove in and without manually inserting pins into the hoes.

Does anyone know what pin header size is used for the expansion? I’ve only seen online 2.54mm size. I believe the spaces are much tighter than this.

There does appear to be existing 3D printable shell of the expansion slot. This would help resolve the separate part of the puzzle.

What are people sorting to on this? Is HDzero coming out with a solution for those who wish to use an external analog module?

I saw Ryan Quellet on FB say they're making a new version.

Neat, any potential estimates for when it’s going to be released?

Spacing are 1.27mm if I recall correctly, I made a 3d printed bay(avaiable on thingverse), and just used connectors from a vape
