About this 3D model

A simple intersection method to implement a flat or truncated teardrop. The 45 degree slope of the sides of a teardrop shape are easier for most printers to produce than a normal circular hole, but the pointy tip of teardrop module in [MCAD](https://github.com/SolidCode/MCAD) is unnecessary for small holes, and can use up valuable overhead clearance that you might need to keep your part small. By expanding on the teardrop module in MCAD, this module produces a the best printable shape while diverging as little as possible from the desired shape of a circular hole. This OpenSCAD library is part of the [dotscad](https://github.com/dotscad/dotscad) project. Source code and full documentation can be found at https://github.com/dotscad/dotscad/
