I wasn't really satisfied with the existing solutions provided here since they use loads of filament and take ages to print. Since I didn't want to waste kilos of filament only to find out that something does not fit, I decided to design my own AMS Stacking System. As a matter of fact, I found out that I actually have two different AMS Models, despite ordering them only 2 weeks apart, so I am confident that the brackets fit two types of AMS with the three cutouts on the sides.

It uses four bracket pieces for each AMS that can be joined with 8x 16mm M3 Screws and Bolts. I added 0.5mm of play to the joints, in case you have problems with removing the supports. Due to this, be careful not to over tighten the screws.

For assembly I recommend tightening the screws only a little to still be able to adjust the fit. Then place the bracket on the AMS and tighten the screws to get a snug fit. This way your AMS will sit very tight in the bracket.

To stack I used some 20mm stainless steel tubes with a 1.5 mm wall diameter that I've cut to length. For me 37cm worked well, it allows to almost fully open the lower AMS lid while it is not too high and wobbly. If you want to use different tubes, the tube and wall diameter are parametrized, however leave some play room, especially when you cut the tubes with a tube cutter.

All brackets use about 500g of filament and take about 16h to prints. A downside is, that this system is not fully modular and does not support more that 2 AMS. Also it is a bit wobbly but not in a concerning way. I've done some prints with this setup and everything stayed in place 👍🏻
