A Bit of Descriptive Geometry:
The Tear Drop.
IMAGES IN THE PDF VERSION.
=========================
If you know the Top Path for the hole, and the bottom path of the hole, how do you scale the hole to be as large as possible, but still with the Self-supporting style of a Home Printer / RepRap Tear Drop” shape?
The Holes on items designed for home 3D printing are often shaped like Tear Drops as it gives a 45° edge which can be printed with minimal problems on a cheap printer with no support structure.
Some designs assume “ideal” situations and are designed with perfectly circular cross section holes.
Others assume the printer can print with unsupported spans of the hole, so have a flat top section, which is not invasive on the “ideal circle”. These designs are intended for Home Print on cheap 3D Printers but rely on the printer having a faster travel speed for “Bridges” – many softwares like Slic3r have independent settings for the “Bridges” Speed.
In both situations describe
