Hey guys, I was fooling around on my redstone world today, and I chanced upon this amazing design! It is only 6x4x2 and it works the same as any other Jeb door.
For those of you who don't know, a Jeb door is a piston door which is made to be flush with a wall instead of being inset one block.
I am fairly sure that this is the first time someone has built this, and I have found it very useful in some of my upcoming maps, so I hope that you guys find good uses for it too!

Additional Notes

Ok guys I have discovered that I am not the first to make this, but I am the first to upload it to PMC. I know that it is not 100% original, I just want to let you know that I did not see anyones video about how to make it. I did come up with this myself. I am aware that sethbling and The8bitmonkey made one, but I was not aware of their videos until I had already submitted the project.
