A solution for stacking two AMS units one on top of the other, and permitting filament changes without moving AMS units or dismantling.
UPDATE: New V4 design available with cross-bracing to significantly improve lateral stability. Assembly guide also provided now.
Dimensions of the stack: Excluding filament / cable entry the two units occupy around 410mm / 16" depth, and 550mm / 21 3/4" high.
Whilst the top AMS may look a little precarious, it appears strong and is well balanced in usage. The stand is positioned directly below the AMS's centre of gravity, and the 90mm / 3.5" top section - with alignment slot - does make it surprisingly stable. Side-to-side stability looks to be okay, but a thicker (than 9mm) section may be necessary for a completely freestanding setup. I'd welcome other users' experiences and feedback.
Warnings:
* Please use the stand at your own risk. I'm responsible only for breaking my own AMS units if the stand fails!
* If the lower AMS has to be removed then the top AMS must be taken off first, as the lower AMS provides stability.
UPDATE: * This works for the latest V3 AMS units. Older AMS versions are not currently supported.
To try to maximise strength, I printed the top arms horizontally with a large flat support section. I've also used PETG-CF. The lower triangle base should not be subject to the same stresses as the top arms, and so was printed in a more practical orientation.
(When preparing the print in latest Bambu Studio (v1.10.1.150) the supports did not slice. I don't know whether this is a known bug. I had to go into 'Support' tab and change the support to 'Type: Tree', slice it - where supports were then shown - and then went back and changed back to 'Type: normal(auto)', and sliced it again. This workaround then correctly slices, with supports shown.)
