*UNTESTED IN THIS VERSION*
"Tier" (www.tier.app) just rolled out their electric pedal-scooters (for rent) here and they miss a smartphone holder (to navigate). There is no way to mount something to the handle, so I made this.
[EDIT] Things just changed here - holders have been retrofitted. [/EDIT]
2nd iteration: Changed angle to get the display readeable, added a brace to keep it from wobbeling.
=> There is no clearance designed in - print the "Wedge" smaller!
=> TinkerCAD couldn't lay the "Wedge" flat properly - do that in your Slicer!
