If your cup holder is too large for your cup, this model will help. The design is such that the model will last a long time if using a temperature resistant filament like PETG or ABS. The model also will not stick to your cups if you input the correct measurements.

Use this fusion 360 model to print an adapter specifically sized for your car. All the dimensions you need are parametric, so the model will generate your correctly sized cup holder if you feed it the measurements from your cup and your car.

The model is configured for a 2003 ford ranger with the center console.
