Gyro cup holder with side walls and optional phone holder

This is still work in progress. Center of mass is still too high, I'm designing a new version right now.

Another gyroscopic cup holder. My version has side panels for better cup grip. I printed the parts with PETG so the side panels are somewhat flexible.

I used 5 M4x16 screws for most connections. The fixtures use 2 M4x50 screws. 7 M4 nuts in total.

The fixture is elliptical, as it was the profile of my friends' stroller. I'm planning to add circular fixture later.

The phone holder is optional.

It's my first published design, so be gentle :)
