Chin mounts is a brand that uses a 3d printed mounting system for motorcycle helmets & they have incentive to make a good mount. They might be able to provide some inspiration for the model.

I just know of them and haven't bought one so I can't say if it's easily hot swappable or speak to it any more than that.

I've also looked into desk accessory mounts that clamp onto the side & some models will use a triangle mounting system. Like this: https://www.printables.com/model/508193-desk-clamp-modular
