  21 * Project description
  22
  23 I felt that original NanoVNA case is too fragile for carrying this
  24 device around in the bag.
  25
  26
  27 [[file:NanoVNA, 1.png]]
  28
  29 Therefore extra protective case was designed:

  31 [[file:make, 2.png]]
  32
  33 Extra surrounding body adds better protection while exposing RF
  34 connectors and buttons.

  38
  39 Also originally there is no housing for calibration and adapter
  40 connectors.

  45
  46 Now there is also stylus / pincers help using touch screen and picking
  47 connectors from the box.

  51 Cover attaches to the body using [[https://www.amazon.de/gp/product/B00TACKU0O/][3mm x 2mm thick neodymium magnets]].

  66 * NanoVNA dimensions
  67
  68 Note: There are multiple variants of NanoVNA. Current project is
  69 designed for NanoVNA with following body dimensions (excluding buttons
  70 and connectors):
  71
  72 [[file:NanoVNA, 2.png]]
  73
  74
  75 | Width     | 86.4 mm  |
  76 | Height    | 54.5 mm  |
  77 | Thickness | 15.85 mm |
  78
  79 Note: About 0.7 mm thick, soft double sided tape strips are added to
  80 back and front of NanoVNA to ensure that it is tightly secured in the
  81 case.
