Lasercut castle

This is a derivative ot the original Lasercut castle by electronrancher, in a layout to cut with 60x30cm plates of 6mm thick.
I had to split up the base plate of the entrance gateway and the baseplate of the big tower, this has the advantage of easier storage as a side effect.
It also fixes some parts in the design.
It does have some extra unneeded parts in the design.
