Snug-fitting cup and phone holder liners designed specifically for a 2005 Corolla, but should work with other 2003-2008 Corolla models. I am aware the top rounded corners of the phone holder liner doesn't quite match the car's corner radius, but the car has different radii from the top and bottom parts and I was unable to adapt my model for it due to my inexperience with OnShape.
In the future I may add a variant of the phone holder with only a thin slot to better hold a phone.
As for the print settings, I used PETG for better heat resistance and a top infill of octagram spiral in PrusaSlicer for a cool floor pattern as seen in my pictures.
