Cup Holder Adapter

cults3d

This is an adapter to let my wife's water bottle sit "in" the cupholder in her car. The car's cupholder is 77mm tall, and roughly 73mm in diameter at the bottom and 83mm in diameter at the top. The bottle, though, is approximately 91mm in diameter. The bottom of this model is conical, to help it sit snugly in the cupholder; the top of this model is slightly conical (bottom is 92mm in diameter, top is 94mm) to let the bottle slide in easily but be loose enough to remove without snagging. The top is just over 67mm in height (the portion that holds the bottle is just over 60mm). The walls are 10mm, and there is a 7mm layer between the upper and lower portions of the model.
