Hey guys, thought I'd share this in case anyone is interested. I didn't love how wobbly the A1 was with the AMS Lite mounted on top, and Aurora Tech on YouTube showed a slight degradation in print quality with it mounted on top as well. However, I really like both the convenience and the look of the AMS top-mounted and liked the slightly forward-angled posture that it had. I decided to try designing a wall mount that would make things appear to be top-mounted in this manner. It worked out really well and is extremely sturdy.

If you'd like to print it, I went with 5 wall loops and 15% cubic infill with small cube modifiers to achieve 100% infill around the wall mounting holes to take the strain better. This is how things are set up in the 3mf files. It's about a 5.5-6.75hr print and uses a lot less filament, overall, than the whole AMS top mount setup. I used standard-style drywall anchors (pan head screw with plastic molly, ¼" holes in the drywall). I put a small recess where the mount holes are in the back face of the mount to accept that small bit of plastic that protrudes from the wall on those drywall anchors. Worked well to allow the mount to sit fully flush with the wall.

Mounting: I recommend mounting it slightly higher than I did, with the very lowest part of the mount flush with the top of the Z axis. Mine's about 3/4" below that, for reference, and can still work if you can pull your printer forward so the spools don't interfere with the toolhead on the tallest of prints. I designed the mount holes with some play so that when you're screwing it in, you can set a level on top of the mount to adjust it perfectly level before tightening things down. There's also a bit of play in the holes that attach the AMS unit to the mount as well, so you can lift one side of the AMS a bit to make minor tweaks if you weren't perfectly level on the wall mounting.
