Build Procedure
3.1.
3D Printing the Enclosure
The first step is to 3D print a suitably sized enclosure using the provided .STL files. If you do not have access to your own 3D
printer, consider visiting your local Makerspace, University, or purchasing a printed part from a reputable 3D printing service.
There are 3 components to print, listed below:
3.1.1.
Main Enclosure
This is the most complex part of the 3D printed
assembly, which houses all the assembled components.
There are separate shelves for the Battery and Bluetooth
module, and dimensioned rails to house the charger
board tray, and the SkyTraq Venus 838 Evaluation Kit.
This item should be printed in the shown orientation,
with the baseplate containing the holes for the switch,
SMA antenna connector, and the charger board at the
bottom. Depending on your 3D printer and settings, this
will take around 4 hours to produce.
