3d Model Refinement for Printable House Facade

I need a skilled 3D modeler to refine a house facade model created with Meshy.ai. The primary goal is to prepare this model for 3D printing.
The freelancer will be responsible for:
1. Removing intricate window details to simplify the geometry.
2. Solidifying thin walls to ensure the model is robust enough for the slicer and subsequent 3D printing process.
3. Performing general cleanup and optimization to ensure the model is print-ready.

The final deliverable should be a high-quality 3D model file suitable for additive manufacturing.
