Description
This 3D analemma replaces the original 2-faced Schmoyer analemma & doesn't require any rotation or alignment to accurately display the time. You just need to read the appropriate shadow edge against the main dial crescent; i.e. left or right side edge, depending on your season.
It uses the same rods from the original design; i.e. 3mm dia., for installation, minus the 2-faced, right angled analemma plates & cone ends. All other parts remain the same & can be downloaded from: Schmoyer Equatorial & Analemmatic Sundial Derivative by 3DMason | Download free STL model | Printables.com
When fitting the 3D analemma onto the ends of the sundial's latitude crescent, the orientation is such that the larger diameter half (or larger teardrop) is situated at the bottom half of the sundial for use in the northern hemisphere. The same 3D analemma can be used for the southern hemisphere also; just flip the analemma so that the larger diameter half is now at the top instead.
Print vertically with no supports & at least 50% infill for strength.
