1. Overview

  • DISCLAIMER: I DO ELECTRONICS AND 3D DESIGN SOLELY AS A HOBBY. THERE COULD BE ERRORS THAT CAN RESULT IN ALL KINDS OF DAMAGE. USE THESE DESIGNS AT YOUR OWN RISK.

I felt that original NanoVNA case is too fragile for carrying this device around in the bag.

Therefore extra protective case was designed:

Extra surrounding body adds better protection while exposing RF connectors and buttons.

Also originally there is no housing for calibration and adapter connectors.

Now there is also stylus / pincers help using touch screen and picking connectors from the box.

Cover attaches to the body using 3mm x 2mm thick neodymium magnets.

3. NanoVNA dimensions

Note: There are multiple variants of NanoVNA. Current project is designed for NanoVNA with following body dimensions (excluding buttons and connectors):

Width 86.4 mm
Height 54.5 mm
Thickness 15.85 mm

Note: About 0.7 mm thick, soft double sided tape strips are added to back and front of NanoVNA to ensure that it is tightly secured in the case.
