The Xiaomi Mijia Mi Sphere is a great 360 degree spherical panorama camera. The companion selfie stick is very handy but it doesn't have a threaded insert to attach it to a tripod. This thing fits on the bottom after carefully removing the end cap (roll the rubber cover down and unscrew the two screws). A 3/8-16 nut is needed to complete this thing, which can be superglued in place.
With this adapter, you can now use the Manfrotto 209 Table Top Tripod (without Head) to take 360 panos without holding the camera. If you have a tripod with a 1/4-20 thread, you can use a readily available 3/8" to 1/4" tripod thread adapter.
Note: No guarantees that this geometry will work for your selfie stick.
