After having had several incidents where my aluminum can fell while braking, I decided to design an improved cup holder.
It's made to accept standard aluminum cans as well as cardboard cups at least up to large (approximately 500 mL).
I've included the .f3d file so feel free to improve on the design and customize it to your needs.
Print as is, around .2 mm layer height is sufficient.
In the included gcode and .3mf I used variable layer height to smooth out the chamfers and fillets.
