Configurable Speaker Port

thingiverse

Speakers with a port require specific dimensions for optimal sound. This OpenSCAD design allows you to change the size and print off the precise size you need. If you use wood-fill PLA, you can sand and stain it like other wood parts. The default settings are for a set of Fostex FE103En enclosures, similar to the ones here: http://diyaudioprojects.com/Speakers/Fostex-FE103En-Bass-Reflex-Speakers/ The external part of the port is built layer-by-layer (with the layer height set in `decorative_layer_height`), which makes the compile take a long, long time. If you wish to change the shape of the external portion, you can play with the formula in `diameter_for_layer()`. This is passed the current layer height and returns the diameter for it. You can use a graphing calculator to play with the formula; the port will take on the shape of the graph. ## Printing Notes Infill isn't important--10% will be fine. You probably want to print it with support, with the internal cylinder side down.
