WARNING! Bambu had revved the AMS and the newest version has a very different side slot sizing. If you have orange first stage feeders you probably have the newer version and this mod won't currently work. You can see details of the new model at:

I needed to make space for my third Bambu printer and I didn't like having the AMS on top of the printer since that makes cracking the top glass to print PLA annoying. So I searched and found a couple of AMS wall mounts. But since each AMS is 5+ kg and cantilevered out from the wall a fair way, I really wanted to screw the supporting brackets into the 16" spaced wall studs and avoid needing two side by side brackets for the 2 internal AMS gaps. The AMS is 15" so it is super close to this width. But that meant I couldn't just print a single bracket + support in one piece on its side on the built plate since the AMS support piece must be offset. And I wanted a different double mount piece for middle supports that would be off both sides. So that means printing the top ‘shelf’ separately from the bracket so I could print it flat.
I found and remixed a nice hexagon shelf bracket. I added a diagonal brace since the hexagons alone flexed way too much otherwise) and added a slot so that the top piece could be printed independently and flat and then simply slotted onto the supporting bracket. This also allowed for hiding the mounting screw at the top. And I additionally modified it so a slipcover can also hide the bottom mounting screw giving a very clean final look with no visible screws.
I also added variants - a middle holder with 5x build plate holder built in and end pieces with built in Honeycomb storage wall by RostaP | Download free STL model | Printables.com.
So, there are multiple pieces to the modular mounting system:
Printing, at least for the brackets, should be done in PETG since PLA will likely creep with the constant weight. I found that one of my PETGs could bridge the slot gap fine another… not so much. So the profiles have supports enabled to maximize the print success rate. The tolerances are tight so that the top pieces don't slide away from the wall when installed so before installing to the wall you should make sure that the fit isn't too tight although. Due to the slight sag from bridging I found the fit was a little variable but even the tighter ones loosened up with a few insertions and removals - just don't use brute force to force it all the way on until you've loosened it up or you may never get it off! The addition of supports should make the prints more consistent and less likely to be overly tight - let me know if you find they've become a little too loose - we do want a bit of friction fit between brackets and mounts.
When installing make sure to measure very carefully to get the brackets exactly 16" apart. There is no slop on the AMS mounts so if you're off too much you'll not be able to get the AMS to sit on the mounts. If installing multiple be sure to measure multiples of 16" from one end instead of individual 16" increments to minimize measuring errors.
Since this is a modular system it is also possible to remix alternative wall brackets to suit your personal style. And alternative top pieces to add additional storage options. I'm working on expanding the options here.
