I've design this AMS stacker to allow me to stack 2 AMS units on top of each other.

The AMS lid can be fully opened and the inside of the AMS accessed without removing it from the stacker.

Printed in either PLA or PETG.

I've added space below the top AMS to store build plates.

I sometimes use hairspray or 3Dlac to spray the build plates for better adhesion, and have added brackets to store the can. These brackets can be fitted on the outside of the stacker in any of the hexagon holes.

The parts must be glued together.
