Added DXF measurement files for the Omega2 Pro, Omega2 LTE, and Omega2 Dash to their respective repos: https://github.com/OnionIoT/Omega2-Pro/blob/master/Hardware/R1.2/Omega2-Pro.dxf https://github.com/OnionIoT/Omega2-LTE/blob/master/Hardware/R1.1/Omega2-LTE.dxf https://github.com/OnionIoT/Omega2-Dash/blob/master/Hardware/R1.0/Omega2-Dash.dxf You can get super precise measurements from these files. Onshape is a decent, free online service you can use to view the files.
