Looks easy! But can you solve it? Airlock by Goh Pit Khiam

Airlock is a 2D restricted packing puzzle designed by one of my favourite puzzle designers Goh Pit Khiam. I made a 3D printed version before it was released and have solved it! (hurray). It has since been released on the Pelikan website too, check it out!
