This is the glyph of Bridge Four from the Stormlight Archives. I printed mine dual color via filament switching with Kholin blue on white. The model will require scaling, and I recommend tweaking the Z-scaling separately to your liking.

The other Bridge Four symbols on Thingiverse are a bit low quality, so I made a high resolution version. The design is modeled after the bridge four patch for sale by Brandon Sanderson: http://store.brandonsanderson.com/bridge-4-patch/
