I decided to use PETG. Printing the model does not require any special settings. See the attached 3MF file for detailed print settings.
Optionally, you can stick protective felt inserts on the bottom of the box and cap. The template is attached in a PDF file.
If you want to modify the model, I am attaching the STEP file and a link to my OnShape.
Please don't forget to leave a rating or a comment. Feedback is important for me Thank you very much.
