How to make an object glow in Studio (BrickLink)
Looks like I solved my problem myself.
Here's what I did:

I exported the Lego model as Collada (.dae), and imported it in Blender. Selected the material and changed Diffuse BSDF (Maybe changed for you) to Translucent BSDF (for cycles only), selected Volume as Emission and rendered.

Cheers
