 * HDMI signal preconditioning with a pair of `PTN3363 <https://www.nxp.com/docs/en/data-sheet/PTN3363.pdf>`_ HDMI level shifters.
 * Signal equalization controlled with on-board DIP-Switch
 * On-board SiLabs `EFM32HG322F64 <https://www.silabs.com/documents/public/data-sheets/efm32hg-datasheet.pdf>`_ MCU for interactive control and board monitoring
 * Supports different EDID connection scenarios
 
 Mechanical layout and dimensions
---------------------------------

 3D-printable enclosure
-----------------------
+======================
 
-There is also a 3D-printable enclosure available in the ``3d-models`` directory.
+.. image:: ./img/3dprint-enclosure.png
+
+There are also 3D-printable enclosure .stl files available in the ``3d-models`` directory.
 The enclosure allows the electronics to be covered and attaches the Video Booster Board to the Numato board installed in a typical thin mini-ITX chassis.
+A connector is the source, B is the sink of the RX/TX signal. 
+
+For printing the enclosure, use slicer settings matching your used 3D printer and filament.
+Setting layer thickness to a value between 0.15mm and 0.2mm is sufficient.
+The image below shows proposed print orientation.

+.. image:: ./img/3dprint-orientation.png

+Enclosure can be assembled with the board using 3 M1.6x8 flathead bolts.
