MP3 Player
I found an MP3 component on eBay, and thought it would be a cool 3D Case project. I mounted a couple small speakers underneath so it switches between speakers and headphones.
The case was printed in PLA, and the ID of the case was printed at the same size as the OD of the MP3 player. The fit was nice and snug, and a mounting bas was printed across the inside to screw to the MP3 head.
This is already going to be redesigned, as I just found an LED Color Organ to tie into this to give some color to the sound. I'll use some translucent PLA to display the lights with, and incorporate a geometric pattern into it to give the lights some diffraction.
