At the moment there are only 3 parts in the planning phase
- corner tower
- wall section with half towers (can join the tower or another wall section to form a small tower)
- gate section
I will get you the exact sizes for tomorrow.
One base should fit on the wall, and two bases on top of the corner towers. The outcrops on the wall section can also take 2 bases (bolt thrower etc.)
By kit version you mean to have 4 tower walls and a tower top instead of two parts (tower base + tower top)??
IF the first tests are successful and there is real interest, then we have more ideas
- ruined versions of the first two (not 3d printing) - will surely be done
- wall without half-tower ends (could also be done using a saw)

- walls at an angle
- extras for the towers (wooden structure upgrade with roof, outhouses, latrine, stairs etc.)
- castle utility buildings (stables, well etc.)
etc.
