6 models
Recently I ran across an article about Helmholtz Resonators and I just had to explore a bit further. The great thing about 3D printing is that I was quickly able to design and print a couple of models to try them out for myself. The…

This is a remix of JoePKrcma's "Hollow Helmholtz Sound Brick". His youtube video lists "And here is the free file if you want to download it and print on your home machine (good luck with the overhangs and support):" The thingiverse model…
The internal mesh of Joe's published meshes are a source of trouble for 3D printing. I rebuilt it so the internal corners are well-behaved. Joe's original design: https://www.thingiverse.com/thing:6384566 Joe's modified design for…
This modification adds a series of Helmholtz Resonator (HR) chambers to a modified enclosed flywheel cage for the Spirit brushless blaster The chambers have precisely-sized holes and volumes targeting the following frequencies: 2x 2000.4…
This is a control device that can detect a 493 HZ tone to control a motor or other device like the Hex-A-Bot dual drive walking robot. https://www.thingiverse.com/thing:3262487 The Helmholtz resonator is what gives the Arduino type sound…
