Thingiverse user Master Aar has supersized the AirPod design to create a massive bluetooth speaker. The AirPod "Max" is over 6x the size of the AirPod. That makes it about 10" tall.
He has laid out detailed instructions on turning it into a desktop bluetooth speaker and includes STEP files if you want to customize it, like making it even larger.
I want to print two of these then hop on public transit holding both of them. I can only imagine what the charging case would look like; it would have to include wheels and a telescopic handle.
If you want to create your own AirPod "Max" then head on over to Thingiverse and grab all the details.
