The front cupholders on my Mazda 3 (2019 Hatch) were not holding things well enough, especially when turning.
This should fit other Gen 4 Mazda 3's that have the same cupholders with a lid.
This fills in the blank space meant to allow the lid to close. Because of this, you cannot close the lid with this installed.
I've used some strong Velcro to adhere it in place.

I've had it available on a different website, but expanding it to Printables for further reach.
The author marked this model as their own original creation.
