(I live in Pewee Valley, KY, not Houston, TX)
This is the 1:48 scale print of the fourth floor. The source is here: https://github.com/sunnywiz/housejscad/tree/Post3 and the STL files you are seeing here are bedroom0.stl, bedroom1.stl, and bedroom2.stl.
Problem: The top half doesn’t quite fit the bottom half. This is because the top half isn’t large enough to hold the shape together – when the roof prints, its warm, and as it cools, it wants to shrink, and so it wants to curve. The bottom print wants to do the same, but the walls are large enough to prevent this from happening.
Solution: no-roof. Which, my wife points it, is the way to go: then you can easily play with the furniture inside. The side effect of that is, in the current iteration, I won’t be doing top/bottom alignment tabs (similar to the “cross” thing on the left side of the picture).
Otherwise, the 1:48 scale is working well. Here is the same bottom half, but with Victorian doll furniture inside it:
The checkerboard at the bottom of the picture is also working well as a place to glue things. Here it is glued to the next piece:
Pretty proud of it so far!
