Trying to export geometry from Unreal using a widget button

This might be an odd question to have, but I was wondering if it was possible to export a mesh from UE4 as something like an .obj or .stl file. The context is that I made a simple tool via Blueprints that adjusts morph targets on an object (sort of like a character creation screen) and I wanted to be able to get the modified mesh back out of Unreal.

I don’t know a lick of C++, so if this is feasible in Blueprints alone, then great. If it’s not, I do have a fallback of giving the user the morph target values that they could input themselves outside of Unreal, but I’d like to eliminate as many steps to this process as possible.
