Weekly Pill Case Lid - Wider Grip

My father loves these weekly pill cases, but does not have the dexterity with his health issues to use the original model's lid. I designed this lid with a wider grip and a slightly increased outer diameter for his fingers to be able to grip the lid more security and twist it to position effectively.  

The original pill case lid now has the chamfer reduced on the outer diameter, along with the diameter slightly increased for a better section to grip and twist.
