Overengineered no spill cup

Descripción

Well i have been using this over a year and im pretty happy about it. There is no adapter for attaching to your driver side but you can attach to the headrest rods. so only back seats can use this but i will include the project file so you can customize the thing. Green line represents the rubber band if its not stiff enough add another one. also some parts needs to be glued but i got so lazy to explain. i think you can figure it out. If you have any questions or recommendations please let me know.
