Can be printed as is, without supports

Mine has been printed with 0.30mm SPEED, takes about 9 hours. 

TWO versions included, one as in the pictures and one “simplified” version without the battlements and without windows (for those who don't care about the looks) 

The design itself is based on the model by Juliuis3E8 on thingiverse. Main difference is that my design is a single piece print and I added some minor tweaks (like the windows) and an extension of the lower feedramp.
