Custom Semi-Circle Ruler/Template

This is a semi-circle/circle template used for specific art projects. It is large and used for up to A3 sized paper.

This was an experiment to see if 3D printing could be used to make custom templates and rulers. The STL and SketchUp files are provided.

While it is not a precision instrument it is good enough for art projects or conceptual illustrations where precision is not a necessity.

Be careful with printer settings because fast and careless prints will result in imperfections especially in some of the circle templates.

The black text was achieved by changing the filament from yellow to black after 2.1 mm of printing (0.3 mm layers).
