I don't have a 3D printer, but I have a wood shop, so I carved a mount for my analog adapter board + TBS Fusion to clip onto my Walksnail Goggles X strap. Works well so far!
It would have been easier to drill the holes for the side where the cords plug in before cutting out the interior. I ended up finishing the profile with a jigsaw, just going very slowly to avoid splitting off the side.
I used a scrap left over from turning a piece of birch.
Hope the kit works well!
The foam is great, and fixes the light leaks I had on the sides with the stock foam. It's NewBeeDrone Max Comfort Goggle Foam for Walksnail Avatar Goggles X- Sponge.
