Description
The small square bastion stood along the eastern rim of the Kingdom wall, a key junction where the upper tiers met the lower. It was a prime lookout not just for invaders on the horizon, but also for any no-gooders causing trouble inside the kingdom.

Low Adaptors Reference

The Level 1 needs to be a bit taller so that the second level is on the same height as the walkways from the H/I Low adaptors. Level 1 + 2 add up to the correct height for Lvl 3 to meet walkways for a standard wall, but using just level 1 with a Lvl 3 on top means it sits below the level of the low walls. I can send images of it mocked up in Prusa Slicer if necessary.

Thanks so much for bringing this to our attention. A while back, we adjusted Level 1 to match the height of the other levels so it would be easier to swap in different levels as the ground floor.
Because of that change, we’ll be adding a step down to all the low Adaptors to make sure everything fits together properly.

Does the balcony have the option to have doors? If not can a version that supports doors be added?

Great idea! will add this to our updates.

The Adaptor-H-Twin-v1.0 is great! you should add it to all bundles with square and hexagonal towers at least! Even if it’s not completely working in the hex system.

Pardon me if you’re still working on it, but everything else seems to be completed so I thought it was time to ask. Where is the ruined version of this square bastion?
Joanne Boorer (verified owner) –
Thanks for reaching out. This was an extra added product that was not part of the original campaign. The ruined parts of the Ruined Millbury tower can be used with this product.
