Remix of original phone tray addon posted on printables. It was very well done and used it as is for a while but found some areas for improvement that makes a big difference during use.

In my remix, I reworked the height and angle of the entire mounting system reducing the tilt slightly, while shaving off about 30mm of height. This results in much less interference with the rotation of the screen causing the fan to hit the phone tray, even when the screen is still tilted forward. Before you'd have to tilt the screen back all the way to allow for rotation of the screen.

Second, on the bottom side of the tray, I added an arched lip to the forward side of the tray which results in much less movement. On the original version, without this lip, the whole tray would vibrate/slide backwards at times up to an inch when the weights were in, and as much as 3-4" when the weights weren't there to hold it in place.

I found the to print best upside down, and used supports with a petg interface layer, and the rest printed in pla. This results in a pretty simple support structure that removes fairly clean and easily. As an additional option, I also printed a very thing .5mm additional platform layer that I printed separately using a patterned print plate for a nice finished look. This optional platform fits perfectly into the top of the tray and worked really well for giving enhanced finished look. I just affixed mine with some thin dual side 3m tape, but glue would work just fine also.
