Before you start:
• Use well calibrated 3D printer as the parts are small and tolerances tight to snap fit.
• If you get lost, look at the scheme of assembly again.
• I prefer quality PLA from Fillamentum for this model, but any low shrinkage material (CPE, PETG?) should work.
• Please, print all of the STLs once, only the window (glass & frame) print twice.
• Proper recommended colours are noted in the file names.
• All parts are designed for 0.2mm layers, only the mentioned main STL ("Masonry-white.stl") and both roofs can be printed with thinner layers (0.15mm is good enough).
• Optional: All of the models are ready to be printed without supports, only the "Masonry-white.stl" can be printed with supported arches and lintels for cleaner result. → Use as little supports as possible! (Nobody wants to clean up such a small model.)
• I didn't have to grind or cut anything on the verification prototype, I just broke off and cleaned up the temporary supports. However, if your 3D printer/print profile is not very accurate and you encounter groove too tight, use a small file and/or a modeling knife.
• Please, be patient. The assembly phase is very straightforward, but some steps (like to insert a window frame together with glass) need to be precise.
