I designed this Tie Fighter and added 4 big cannons to it as I always thought it lacked fire power.
I followed this tutorial below as I'm still learning Blender and it is technically my first model successfully designed and printed:

It's cool a little model to practice a lot of techniques.
You will need supports and you can use the fill feature in the slicer to select which parts to support, I added the orientation image to show how I printed mine as a reference. As well, I added pictures of the supports that work for me.
I put the supports below so that way the delicate parts don't need supports and create a chance of destroying something.
The author marked this model as their own original creation.
