Dodecahedron Speaker Build | Shapeoko 3

I recently finished building a dodecahedron speaker and finally got around to writing it all up. Here is a short slideshow of some of the build process and general photos. For the full build-log please check out the Instructables post here:

My main goal here was to challenge my skills, not only those few hand skills I have built up as a maker but also pushing my ability with my CNC to a new level with large parts  needing to be machined accurately and quickly. I built on what I learned from my last speaker build and applied  it to this project to make it as good as it could be. Naturally I still have a lot to learn as a maker, but this project has definitely taught me a thing or too to which will help me on my design journey to bigger  and better things!

This project gradually took shape over a few months and the speaker drivers themselves were kindly provided by

I am getting back into the swing of things with my blog so hopefully I can get some good quality content on this blog for you, the reader, to enjoy 🙂

    This is outstanding! I really want one of those CNC thingys! I wanted to do this same design for years but couldn’t figure out a way to cut the angles. The best I could do was a five sided column or prism.

    Your speakers could use one of these to take out the response and room irregularities:×10-hd

    Dang dude, how do they sound?

    If I were you I would do a search of patents, trademarks, and copyrights then go into business.

    Use better (kick ass) drivers and… maybe a set in walnut? Padauk? Rosewood?
