Do some 3D Modelling

Design 3D printable models of land (African Terrain). Model 1: 1sqaure meter African bare land with vegetation mountains and some animals Model 2: 1square meter half baren land under development. The following are to be visible: 1. Land being cleared 2. Work on power-lines being installed 3. Work on sewage pipes being installed 4. Roads under construction 5. 1 house at foundation level with work being done 6. 1 house halfway constructed with work in progress 7. 1 house completed with car parked and kids playing around the house Model 3: 2x1 square meter urban setting. The following are to be visible: 1. A high density residential area 2. A low density residential area. Some houses in the low density area should have boreholes, solar panels and some with swimming pools. The low density area should also have a police station, clinic, school, church and communal grounds
