This is a hook for your bag to the ninebot KickScooter E2.
Internal diameter of the design is D34,4 if you wanna check if it fits to other scooters.

Material: petg
Fasteners: 4pc 4x25 mm wood screws

It should be printed standing as it is. The bottom fillet is different to be printable.

Hope it will work as well for you as it works for me.
