Hey uh- I kinda did ask this on the video but I do doubt anyone would get back to me on the video- I was wondering that, in the video of the Custom Tardis Add-ons Tutorial that uh, how you would be able to get a Tardis model, due to how in the video it's shown one. I was just asking if there was anyways to get a model of a Tardis for blockbench instead of making one, since it'd be hard to get the proportions right to match the game.

 If you are familiar with resourcepacks already, then you can just do this:
Extract the dalekmod.jar (name will differ from your version) as a .zip archive, .jar files are just zip archives with another extension so the user and computer knows that the archive contains java bytecode and other assets related to the java program.
After extracting it, you will have you assets/ folder and inside there you can find the TARDIS Models somewhere

unzip the mod's .jar file, one of the folders has the tardis models so just drag and drop one of those .json files into blockbench and then voila
