I couldn't find a Oculus Rift S mount that hung it lens-down and was stable, so I made one.
Modeled off the stripped down Rift S base. See pic
Inadvertently it also fits the Rift CV1 and the Quest. As these two both have a webbing between the outside of the lens and the edges, it still holds at 3 points.
Designed to be printed without supports.
2x 5mm bolts or screws are needed.

EDIT 1: Added screwless versions. Due to the weight, I recommend you get a damn good mounting tape. I added a less risky version too with the oculus logo to give mounting tape some more purchase.
EDIT 2: A few people have mentioned that the Rift S is detecting the mount via it's sensor. I have uploaded a version that should be well clear of it. I haven't printed or tested it personally.
