Dave, did you ever try this out? I'm about to bite the bullet scaling up for my holey baskets.
I was going to print that out and changed my mind. I could not get over the the chamber covered up 70% of the horn mouth, maybe that was not an issue. So I designed this to print in one piece on my printer. I have printed a few pairs. The drivers are Eminence alpha 8. These are 2 inch speakers and are 8 ohms.after checking out Acme Klein Bottles i was wondering if the shape could be used as an enclosure for a fullrange driver possibly creating a backloaded horn assuming an exit is created.
i do want a klein stein for a beer mug!😛

Very nice! I bit the bullet and am printing a scaled up version of the Klein Bottle to use with the Coral Holey Baskets. I only have PLA basic on hand, and did a 25% infill just to see if its worth bothering with a better filament and more infill. Have you measured with different filaments on your multiple versions?
I printed them using basic PLA. I have not measured them all. I used 25% infill on them. The walls are 8.5 mm thick. Wonder how big you need to scale them for the holey baskets. I printed a a pair of open baffles for my holey basket. I found out one of them was damaged. It sound like the dust cover has loud screeching sound to them when pushed them in wattage.. here is a picture of the open baffle. The baffles were spherical shaped. The one damage speaker I could not stand listening to them.

I have the stl file for it open baffle. you will need a 400mm by 400mm printing area or at least one side having 400mm length. also my printer has a print height of 450.0mm.
@ Dave, the surrounds are supple not stiff at all. the one speaker makes a screeching sound. the other sound great. the one is damage I believe, the dust cover was pushed in and I sucked it back out using a vacum and that may have damaged it.
I think i only heard one pair with supple surrounds. Outstanding.
I hop you can find another.

Most people that have found their way into or onto a very large Real Klein Bottle . . .
1. Do not know where they began; and do not know where they will end.
2. Can only scratch the surface.
It is all just Math.

Did you know that if you cut a Klein bottle in half along its length, you get two Möbius strips?
Come with me as we enter the fourth dimension!
Galu,
Thanks!
I will see if I can "find the time" to contemplate the cutting of the Klein Bottle.
My dad had Mobius Strips in his feedmill.
They transmitted power from one wheel to another wheel.
Having the Mobius "Twist" in them meant that the edge wear and tear, and the surface wear and tear, . . . was equal all along the strip.
Lastly, you never see two doctors together, that would be a Paradox.

Even better with your edit!
I present you with another 'paradox'.

I was referring to the 4th Dimension, Time.
I am not always able to move or slip into that.
And for music fans, not that good singing group, they were called The 5th dimension.

Print is done, and I couldn't wait to try one out. I had to print in two plates and reassemble since my printer isn't that large. Its paired with the sibling holey in an open baffle.
Hard to make any real observations at this point except that it makes noise and looks great 🙂
