Yet Another Customizable Table Sundial
Description
Since I had no experience with OpenSCAD, I started with doctec's sundial to learn from designing a real life object. I didn't understand much and started to eliminate things to get to the bare essence. After that I built my own dial. Thanks for the introduction, doctec! My sundial will work nicely on the moderate latitudes on the northern hemisphere. This version doesn't work in the Southern hemisphere. For this sundial some thoughts have been leading: + When the sun is at it's highest point, it is positioned exactly South (or North); + The 'sun revolves' in 24 hr around in a plane perpendicular to the Earth' rotation axis. + The elevation of the sun at its highest point may vary through the year; + The gnomon can be made as thick as desirable without distorting the time reading. <br> Since the dial depends on your specific location on Earth, it is useless to place stl files with this posting. You'll have to generate your specific model with OpenSCAD yourself. This is not difficult! * Download HorizDial.scad from thingiverse.com (and remember the download location); * Download the OpenSCAD installer from www.openscad.org; * Run the installer (and remember the installation directory (for me (Win10): C:\Program Files\OpenSCAD) * Run openscad.exe from this directory; * Open the file HorizDial.scad in OpenSCAD; * Adapt the variables 'label', 'latitude', 'longitude' and 'timeZone' for your own situation. Instructions on how to find the correct values are in the source text; * Generate your own sundial bij rendering it (F6 or 'Design|Render'). This might take a few minutes (watch the progress bar down right); * Export the sun dial as a stl-file (F7 or 'File|Export|Export as STL...' ). Chose an appropriate directory and filename; * Use this stl-file as input for your slicer program.
