Configurable Speaker Port

thingiverse

Speakers that use a port demand specific dimensions for optimal sound quality. This OpenSCAD design lets you adjust the size and print off the precise dimensions you need. If you utilize wood-fill PLA, you can sand and stain it like other wooden parts. The default settings are for a set of Fostex FE103En enclosures, similar to those found 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 very long time. If you wish to change the shape of the external portion, you can modify the formula in `diameter_for_layer()`. This function takes the current layer height and returns the diameter for it. You can use a graphing calculator to experiment with the formula; the port will adopt the shape of the graph. ## Printing Notes Infill isn't crucial--10% is sufficient. You likely want to print it with support, with the internal cylinder facing downwards.
