4" Egg Speaker

Changelog:
2019/03:
Changed bass port to minimize port noise and get a bit lower bass, foam pad needed now is also smaller and has to be placed under port opening in the bottom of the egg.
New model comes with less support also, but you will have to use support blocker as pictures show (blue = block support), if you get support under + and - in the back then block that also
2018/12:
Updated design to fit Ender 3 printer build volume (medium poly only now)
2018/09:
* Added a rod in the top that connects bassport with top of egg reducing resonance and
removes the need for support in the top
