I felt that original NanoVNA case is too fragile for carrying this
-thing around in the bag. Also originally there is no housing for
-calibration and adapter connectors.
+device around in the bag.

-[[file:make,%201.png]]
+Therefore extra protective case was designed:
-This body/case provides better protection for device.
+[[file:make, 2.png]]
+Extra surrounding body adds better protection while exposing RF
+connectors and buttons.

-While external case helps to carry this thing around in the bag, by
-covering touchscreen and housing calibration and adapter connectors.
+Also originally there is no housing for calibration and adapter
+connectors.

-Stylus / pincers help using touch screen and picking connectors from
-the box.

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

+* NanoVNA dimensions
+
+Note: There are multiple variants of NanoVNA. Current project is
+designed for NanoVNA with following body dimensions (excluding buttons
+and connectors):
+
+[[file:NanoVNA, 2.png]]
+
+
+| 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.
