Tarot main plate 650

i made this for fun, i have a tarot rc drone, a large one, and wanted to make a copy i found most parts in here but not the main plate, i am not a designer so i did my best,
i took a photo and with mesurements, and used photoshop, and made an extrution i 3d, it might not be perfect, so if any one wants to make a better version you should :)
the first print i did it was way to large so i sized it down, then it was a tiny bit to small, i have not printed a third model, but the mesurement should be ok now,

edit i made it from a scan aswell, i its more detailed, and more correct, you choose yourself ;)
