I've always been fascinated by sound, music, and frequency. So making a phone sound amplifier was high on my list of things to do. After many prototypes, I came up with a design that works fantastic and is hopefully easy to print.

Shaped after a spiral shell, this little speaker will seriously boost the volume of your phone speaker! Not to mention, it doesn't require any electricity. It would be a great item to bring with you on a camping trip.

I designed it to be wide enough to fit most phones, with generous space from side to side. The cutout in the shell is also big enough to capture the sound from most phone speakers. So fitment shouldn't be a problem for most people, and I can always make variations if I receive feedback that it's not the right size.

This is a fun item to print and show friends when they come over! Try it out, and let me know what you think!

Printing Description / Settings

Tested with PLA; not tested with any other filaments.

Use 3 Walls.

Scalability

Can be scaled up and down a bit. Be careful when scaling down, because your phone might not fit in the holder.

Supports Needed?

Yes, on the build-plate only.

** If your printer does not have good cooling, I recommend painting supports underneath the large opening where the sound comes out. A few strands of filament can sag down if you don't add supports.

• I will include a 3ML file with all the proper settings so you can easily print.

** If you have a machine like the X1C, you should be able to print this with only supports on the build plate.

Further Printing Notes:

If you are having trouble with the bottom rounded portion of the print, try using variable layer height to smooth out the print.

Thank you again for all the support, and I hope you love the speaker! Let me know if you would like to see any other speaker designs! Happy Printing!

Sincerely,

Kevin
