A note of caution, the uZeus is designed to be mounted on metal rails, and while it is possible to mount them on 3d printed plastic, it's not ideal, and if you ask TipTop I'm pretty sure they will recommend against it. However, I've got a couple mounted on 3d printed plastic (albeit not in an actual case) and what I've done is put these heat sinks on them to dissipate any excess heat:

Actually since the heat sinks and tape are cheap, I've gone ahead and put one on all my uZeus modules, regardless of where they're mounted. It's super easy.
