#3DPNSpeakerCover. My idea is to have the main body printed out of any filament but the inserts be printed out of something like Ninjaflex TPE. The thought is that when the speaker is vibrating it will move the mini speaker's and it will look like a mini functioning speaker. If it changes the sound then you can just take out the inserts and leave it open. Also, the speaker cover is upside down for some reason on Thangs and is showing the bottom side of the model.
