This is my attempt and improvement of one from Amazon. The front hole has a curved bottom to make it easier to get paper clips out. The Amazon version is here:

I made this with TinkerCAD and there are a couple artifacts where the paperclip hole joins with the pen hole. Any assistance with making that better would be appreciated.
