Commercial 3D printer businesses?

[Highpower]

Actually I was thinking about it all wrong anyway. I was picturing the tray being printed flat on the bed with the downspout pointing up from the bed. I thought the supports would have been located between the 'bottom' of the tray and the round mounting rods. I was mentally looking at it from the wrong angles.

I don't know how you guys do it. After watching a few random videos on 3D printing the number of variables involved are staggering.
