The problem: Insta360's new GO Ultra uses a redesigned magnetic mount, so none of the GO 3S accessories owners already bought (magnet pendant, pivot stand, easy clip, quick-release mount) fit. Insta360 confirms they are not cross-compatible, reviewers call it out as a con, and owners in the GO community are frustrated about rebuying every mount.
The challenge: design a small, low-profile bridge adapter that holds a GO Ultra securely on one face and seats into existing GO 3S magnetic accessories on the other. Think 3D-printed PETG body with press-fit neodymium magnets and/or a mechanical latch. It must hold through walking and light action, keep the lens and buttons clear, and be easy to remove.
Deliverables: CAD (STEP plus STL), a printed prototype tested on both a GO Ultra and GO 3S accessories, and a note on magnet sizes used. Good designs may become a You3Dit Shop product, like our 3x3 GoPro mount adapter.
