This is a piece of a Stargate from the SG-1 series. I designed this to use it as a "face" for my headset support. It has very small details and is best printed with a 0.2mm nozzle.

This was not made in any exact scale, and it's not an exact division of the whole circle (if you put 9 of these together it will probably not form a full Stargate). I just got an SVG drawning of a Stargate and simplified it on Illustrator until Fusion 360 was able to handle it without having a seizure.

I will not post the design for my support because ot was made specifically for my window and would not fit anywhere else. If you want to use this like I did, the inner circle radius is 295mm, and the outer radius is 330mm. Therefore, the height of the gate section (excluding the chevron itself) is 17.5mm if printed at 100% scale.
