3D Printed Doof Doof! (Phone Amplifier)

I’ve always been fascinated with the way putting your phone into a cup or bowl can suddenly improve the sound quality and volume. Even a simple cardboard tube will work (check out this video if you don’t know what I’m talking about). Being a bit sick of having no real spot for my phone on my desk, I thought it was a good time to have a go at 3D printing something that would both hold my phone and improve the sound when I’m playing music or just when a call/text comes in. Yes it’s been done by many others, but of course I want my own unique design!

The above video is the outcome of about 4 hours of printing on an ‘Up! Plus 2‘ 3D printer (0.2mm layer thickness, <10 degree support), showing how little support material was required and that it works straight off the printer. I swapped filament colours part way through printing to create the multi-coloured effect, following on from my last post.

In the video you’ll notice the phone doesn’t really sit in place properly – I forgot to add a little rib to stop it sliding forward. However I have since glued a small piece of scrap in place, and updated the STL file to provide this feature (photos on Thingiverse). Of course I have shared this design for FREE on Thingiverse so you can print one for yourself, just click here to visit the page. As always if you make one I’d love to hear about, please share comments/photos either here or through Thingiverse.
