new for 2026: bambu ams 2 rack

A while back I released a few mods to an existing Bambu AMS print and included my own extruded frame design. It did the job, but with the cost of parts rising, and with some experience of using my own design for over a year, I have made some improvements - and some simplifications.

The original design improved upon another maker's 3D printed shelves for holding the Bambu AMS (1?) units, and they did fine- but the prints were time consuming and fairly costly from a filament perspective, but nothing too bad- but each shelf needed a large, structural part printed - 4 parts for each shelf. My change to the design was simple at the time, to make a handle that printed without supports.

You can read more about my old design here, but I wanted something simpler, and maybe even a little bit cheaper for my AMS 2 units, since they have a key change- they have an exhaust port on the bottom/back, and they recommend not using plastic as a shelf material.

That's ok, since I am getting some hours in with metal part design, so I started building out shelves and pricing out the design with online vendors. What wasn't ok was I quickly ran into a number of issues around cost- and so I challenged some of my assumptions about what I really needed.

This led me to eliminate the drawer assembly entirely. I didn't like that it was top heavy if you had a full 4kg of filament on the top shelf, then emptied the bottom, or simply slid the bottom AMS out- it was precarious and while I just needed to be careful, I didn't enjoy always being on guard around one of my own designs. So I sacrificed some vertical space and just made the entire unit a few inches taller to accommodate the bottom AMS 2 unit opening.

I also made the units drop-in as before, and made some notches for the vents and other workings. After that, I wanted to optimize a bit more- so I tried to see if I could use the same part multiple times in the design, since online vendors frequently give discounts to multiples of any given part. For this design, the sides and the back are all the same part. The top and bottom shelf are identical too of course, making the kit considerably easier than assembling the old shelf with aluminum extrusion and channel nuts.

For this design I also use Send Cut Send's service to use M5 nut inserts into the frame, so there's just the simple matter of assembling some M5 screws with a hand tool for the main frame. I designed some 3D printed feet to keep the metal frame from scratching the countertop too.

As always, the designs are available here for you to download if you're a paid member, but I also have a Send Cut Send marketplace with the order ready to ship to you directly from them. It's not anodized or powder coated to help keep the cost reasonable, but you can paint them yourself pretty easily.
