Update 09-28-26: Added parts to the detention block. If you have already printed the center section and hallway, these pieces can be added without having to remake anything.

For 3.75 and 6 inch figures.

The hallway is made of repeating parts so you can make it as long as you want. Print only the right half if you want to display it sideways as a cross-section.

The grate is included as a normal version and a blasted one.

A smaller version of the hall can be found here: https://www.cgtrader.com/3d-print-models/games-toys/toy/star-wars-detention-block-corridor-diorama-for-action-figures
