Fan Grid Concentric Holes Generator

thingiverse

Sometimes, when crafting a device, designers often find it necessary to add one or more cooling fans to improve performance. Because the fans must be able to expel air freely in and out of the external environment, technicians need to carefully drill precise holes into the surface of the casing that they are about to design. There are generally two viable options for creating these airflow pathways: 1- Drill a compact circular hole with a diameter marginally smaller than that of the fan's impeller, providing sufficient space for securing a protective grille 2- Drilling multiple, slender holes or slits directly into the body of the case itself allows air to pass through, thus obviating the need for mounting additional protective structures and components. In most cases, the second option proves preferable due to lower production costs and easier assembly processes. A handy OpenSCAD script is available that enables designers to create the precise 'negative' counterparts of these holes and slits. This script produces a series of custom solid objects based on input parameters, which can then be applied to puncture the surface of their designed casing.
