This is my battle-damaged basestar from Fantastic Plastic in 1 /4050 scale.  This kit comes as a complete basestar that you see in most of the show up to Season 4 and it does come with battle-damage arms ,but I did not use them and made my own. First, I made my own raider slots by burning them in with a soldering iron that I adapted the tip for. Then I i used the same thing to do window spots.  Then I mapped the damage to the screen caps and did the work to them to make it look the same.
