The first floor of the watchtower project is printed and temporarily assembled. Everything fits and lines up nicely, and the door swings well. Obviously still needs a coating of paint to bring out the details, but that will wait until the full assembly is done.
Biggest issue this had (other than general printer problems) is a bit of warping in the first few tiles. This is causing the base to be a bit unbalanced, but not bad enough that a proper mounting on some chipboard or similar can’t fix it.
