I got sick of seeing the little hockey puck so looked for an interesting cover but there aren't many around so came up with this, may do some others to follow.
Update - added the eyes, looks way better (they just glue on top)
*Update 2 - New base with 3 rows of teeth to closer match the futurama version, beware the supports on this are a pain to remove
It seems to still hear me ok and the sound is a little better and not muffled.
feel free to remix.
I am planning on doing some light tubes to guide the blue up to the eyes better as at present it only really works when your at the right angle
The head is originally from this rather fine model - https://www.thingiverse.com/thing:18261/files
Supports are needed but beware as they are difficult to remove in places, I used Cura and set up support blocking in the rear grill which saves a lot of cleaning.
