Build a spine of 8 atoms, a cap of 5 atoms, a door of 3 atoms and a key of 5 atoms and assemble them together.

There are not a lot of ways to build the spine and swing it into the right direction with a corner arm 2 can hide into and with arm 1 in a place not blocking building the key. The swing of the spine covers all hexes in arm 2's chamber, and arm 1's chamber needs to hold all the glyphs. It seems that the door can be bonded to the spine during the swing but that would leave no space to build the key too.

The layout makes it hard for communication. Arm 1 can't touch the input and arm 2 can't touch debonder or duplicator. It's fun how they still get to help each other move the part at the far end. Arm 1 moves the spine to bond with the cap to save arm 2 bending backwards to push the cap. Arm 2 pushes the door as the only way to move it past the debonder.
