How NOT to build with Dave! MAD Gaming Terrain Large Wall Vent

It's got no instructions! Well none i could fine.

Oh! The layouts changed!
You forget to post a video one week you wander back and everything’s been redesigned!
Humorous intro aside, shall we cover what this one is about?
I said I was done with MAD Gaming Terrain Videos, especially when it came to “The Complex” I am not done with using the terrain their stuff is great and really versatile, I was just done with making videos on them for now. Well I thought I was, as I was looking for the “Large Wall Vent” instructions I realised there weren’t any. So after spending some time working it out and building the first one, I grabbed the camera and then walked through building the second one. As always with my “How Not to Build” you’ll see me get it right, get it wrong, discover something I missed in the learning stage and then finish with a really nice looking Air vent to replace the parts of my Gothic Residence allowing me to have an industrial block as well as a Habitation block. I have typed enough, just go enjoy this latest video.
