The dish is printed. only thing left to do is add the center mount, metalize the dish, and place the feedhorn.
The diameter of the dish is 49mm, which means the depth of the dish is 6mm. We're dividing everything by two here (units are arbitrary), so the feed horn must be 25mm from the bottom of the dish. This means the feed horn must be 19mm above the 'points' of the dish.
