Update 12-31-25: New parts added. As shown in the pictures, with these additions, the hangar measures 102w x 29.4h x 76"d (260 x 74.8 x 194.5cm). It's fairly modular though, so you can make it almost any size you want.

For 3.75 inch figures.

The wall parts are divided into top, bottom, and middle rows so you can decide how tall you want them to be. There are several detail options for the column pieces on the two bottom rows that can be arranged however you see fit.

Parts diagrams are included in the folder to help with construction, but if anyone needs help putting it together, let me know. Hopefully, I explained it well enough with the pictures.
