Updated: With some MacGyvering, I was able to get the speaker working with a 3D pen and some glue. It still isn’t the best, so I need to reprint parts and rebuild the cone portion. But I have added a video of the working speaker to this post.
Earlier I published the results of my prints from the April 2021 Alien3D UFO subscription box. While I showed off some of the printed parts for this month’s project in that post, I didn’t show the finished product. In this post, I will briefly show some of the pictures from the build process. The project is a speaker designed by @polymate3d and a custom Alien3D speaker case designed by @DSK001_3D.
I don’t have a video of the finished project. Before closing it all up, I successfully tested the speaker (I should have taken a video then). Then when assembling the case, I was using a pick to remove some strings from where the speaker screws into the case. My shaky hands snuck up on me, and I completely tore the cone apart. So, I am reprinting a couple of parts and will post a video of the working project at a future time. For now, I think a few pictures of the build process will suffice.
Instructions I used
I downloaded the PDF with the instructions from the Prusa Printers page for this project. I also watched the YouTube video Polymate 3D posted making a similar speaker. The instructions in the video were not precisely the same. But they were close enough to give an idea of what to do.
To print the parts, I followed the settings on this page of the Polymate 3D website. I mentioned previously that I broke the cone. I think I would have been less likely to do so if I had used a .5mm nozzle diameter as recommended on the page. I used a .4mm nozzle, and I think that caused me all kinds of issues.
Pictures of the build process
I won’t do step-by-step instructions. This is just a few pictures of the build process.







Final thoughts
I love this project. Even though I messed it up after getting it working, I still love the project. I’ve never actually built a speaker from scratch, so that is another thing off the bucket list. Plus, things always go wrong on make projects. The fact I messed up my final project doesn’t mean a failed make in my head. It just means I have to continue the make process and learn from what caused my setback.
Song of the Day: Sadeness
Many years ago, I would do stereo installations in cars on the side for money. I would often use the MCMXC AD album from Enigma to test my installations. This track, in particular, is excellent for showing the quality of an installation.
Bonus Song: Africa
The range and musical offerings from this classic Toto song also worked great for testing stereo installations. I was never a big Toto fan, but I have to admit they created a perfect-sounding piece (quality-wise).
