Xiaomi M365 tire valve adapter

thingiverse

This will make it super easy to attach the pump extension that comes with the Xiaomi Mijia M365 electric scooter, keeping more air in the tire at all times. *PRINTED IN TPE/TPU*, the inner diameter of this STL (9mm) is smaller than the metal connector's (10mm), making it a press fit. You can try using rigid materials scaled up 110% or more, though I haven't tested that yet. To use it effectively, cup your hand underneath like in the picture, apply pressure upwards against the adapter and pull your hand away quickly to get the best results. It's best to start unscrewing right before you hear air escaping. You could also use a string or flexible strip of material if it's still too small for your grip, just like starting a lawn mower. If I made the diameter any bigger, I figured it would take about the same amount of time without the adapter. Please check to make sure your scooter is part of the M365 recall that started in June 2019 at https://www.mi.com/global/support/mi-electric-scooter-recall-program/.
