This is the Starfleet Insignia of the 2390s in Star Trek as seen in Star Trek: Picard, Voyager (slightly different there) and several others.
I couldn't find a fitting model to print online, so I just created one.
I firstly reconstructed a vector file in Adobe Illustrator using this file from Memoy Alpha as a base.
Afterwards, I exported the background (the two colums) and foreground motives into two seperate DXF files.
I had problems with the extrusion not creating a solid object when using a single, combined file.
Following that, I imported the two DXF into two seperate draft layers in Fusion 360, creating the extrusions from there, adding some chamfers and exporting it as STEP-File.
Slicing has been done in PrusaSlicer 2.5.
I created all the files myself as a fan of Star Trek and am not associated with CBS or Paramount. STAR TREK and related marks are trademarks of CBS Studios Inc.
The author marked this model as their own original creation.
