Cup Holder for Car

This is a cup holder I designed for my car for when I do food delivery, as an extra bonus you can fit a 4 cup and a 2 cup size into a standard Door Dash bag. There is a 2 cup and 4 cup variation. They will fit on an Ender 3, however in Cura you may need to use the Ender 3 Pro profile to get the 4 cup variation to fit.
