This is an exceptional and wonderful model.
A minor complaint: Over half way up the hollow cylinder in the base, it tries to bridge a thin disk across the interior, and then again about a half inch farther up. It seems to serve no purpose and it is a potential source of clogging the nozzle and/or breaking loose and ruining the model. Either put some support under there or be prepared to standby with a small paddle to push any loose stringies down out of the way.
All parts were printed with PLA at .2mm resolution. Overall size is approximately 10" high and 6" across.
The base and tower were scaled at 82%.
The roof was scaled at 200% and used a cylindrical support.
