My first attempt at making something from scratch. Based off of Quicksilver's shirt logo in Uncanny Avengers #1 (2015). Chuckled every time I saw it through that series.

I'm teaching myself how to create 3d objects so this is probably not the most efficient way to do it. Started off with a basic triangle in OpenSCAD to get one triangle. Used the native slicer software that came with my QIDI printer to create two more with varying heights. Dropped that into Meshmixer where I merged them into a solid and added the hole (negative boolean cylinder).
