LiteVNA64 Box Insert is a wonderful model. I wanted to add a stylus and made some small modifications. 

- A stylus and stylus holder is added. (The stylus holder is mounted to the LiteVNA with a  thin double sided tape)

- Upper box is revised: 

• Middle wall is revised for compatibility with the stylus 
• I use Female->Male SMA adapters to protect the ports. Needed to extrude some extra space for the adapters. 
• Deeper calibration standards holes
• Extra area under calibration standards
• Some small modifications
