Nitro Engine Active Cooling Shroud

I'm currently working on a project I've dubbed µGen, to see if I can make a useful miniature generator out of a nitro RC car engine I bought online.

However, because the engine will be sitting still instead of flying through the air or along the ground, overheating quickly became a problem.

But I couldn't find anything online to provide cooling whilst the engine was stationary.

Fortunately, this is PRECISELY the situation that I bought a 3D printer for.

I got brainstorming in Tinkercad and eventually came up with the idea of a clip-on shroud to hold a couple of spare cooling fans I had lying around from another part of the project.

The rest is basically history.
