Stone Narrow Bridges model 3d

For a basic bridge, you will want to print: 2 arch sides - bridge_arch.narrow.stl or bridge_arch.narrow.magnetic.stl 2 arch tops - bridge_top.narrow.no_wall.stl or bridge_top.narrow.no_wall.magnetic.stl 2 ramps - bridge_ramp.narrow.no_wall.short.stl or bridge_ramp.narrow.no_wall.short.magnetic.stl to lengthen it (per added arch), print: 1 arch span - bridge_arch.narrow.span.stl or bridge_arch.narrow.span.magnetic.stl 1 arch span top - bridge_top.narrow.no_wall.span.stl bridge_top.narrow.no_wall.span.magnetic.stl to raise it (one inch) - good if you are using pink insulation foam: 2 bridge_base.narrow.stl or bridge_base.narrow.magnetic.stl 1 per arch span - bridge_base.narrow.span.stl or bridge_base.narrow.span.magnetic.stl
