There is also a cutout for your phone when its not used for a drink. Fits a phone with max width of 74mm. Also allows the phone to be leaning at a slight angle to give a better view of the screen.
Prevents (some) spilling of drinks when doing fast 0-60 :)
There is also a 250ml version
Uploaded in 3 different render colors just to show the design a bit more.
- Update: there is 2 more versions uploaded, slightly larger inner diameter. Useful if planing on some form of paint to cover the inside.

+2mm extra diameter (61mm total diameter).
Any is fine PLA
