Step 2: Building in Rhino
A recent instructable I created provides engineered PDF blueprints for modeling a functioning Nocturnal Stardial of your own aesthetic design.
This downloadable PDF below can be cut apart with scissors and assembled with a rivet or eyelet into a functioning paper Nocturnal Sundial. Instructions for that are to be found in my instructable "2d Nocturnal Celestial Stardial TJT1/6" found at:
However, if you are prepared for some 3d modeling, then this PDF will give you the engineered, basic architecture from which you can create a unique, and functioning 3d model.
