Lego Compatible Building blocks Masonry wall

Hello dear builders! I wanted to make a backdrop for a particular scenic area of my Lego city that will run along a railway line. Located at the very back of my build it does not need to stand up to close inspection and much better than empty space. However the print quality and fitment is not bad at all and can be used elsewhere if walls were required. The bricks will fit on standard Lego studs, but they are very tight, this is by design as I wanted to keep the costs as low as possible and they are printed in PLA Plus at .2 layer height. 

Updated, 1x8 Base to Lego, this is a good fit to baseplates (you can build up from there). Arch reloaded is a better fit than the original design. The 1x8 locker will hold the two faces of the main wall body, the alternate gaps can be filled by a 1x2 and 1x4. 

Added 1x3 slope. 

Comprising of everything you could ever want to build a wall. The Masonry Arch Bricks are a non Lego design, two studs wide and featuring the masonry brick pattern. You will need supports for the middle of the arch only. The 1x1 stud on side will need support at the bottom of the stud. Everything else can be printed as is (Some minor droopy stringing on the internal holes of the slope, but these can be safely ignored).  

You will see from the photo how I personally intend to use these (roughly thrown together, this is not a finished build!). The 1x1 stud on side is to add ivy to the walls in various places for some added depth and interest. 

Hopefully this will give someone a small amount of enjoyment!
