3D printed 3" Egg Speaker

[planet10]

Nice eggs. I have been doing a lot of mental gymnastics about how a 3D printer can be used beyond just printing a ‘regular” cabinet in an unusual shape.

While 3” will never be a bass monster, its other assets are very dependent on the driver…

And power handling in a hifi speaker is largely irrelevant.

Very nice! Resembles a speaker that a - now extinct - German electronics DIY magazine has published in the 1980ies.
Best regards!

Love the feet but why 4 of them? Possibly one at the back shaped like a stubby tail? LOL, is this a troll thing? (folklore, not internet thuggery).

Reminds me of the Focal Egg kit that was sold by Madisound back in the late 80s. IIRC, the enclosure was fiberglass, vented, 2.5 way (7N402DBE DVC woofer + T121 inverted dome tweeter?). Sadly, I no longer have the literature on it. I cleaned out my old audio catalogs some time back and that must have gone to recycling.

There was also a Canadian manufacturer, Waveform, building a 2-way egg that nestled into the top of a truncated pyramid hosing the woofer. Try-amped IIRC.

Yes, that was exactly the kit I've meant in #12! Thanks for reminding!

Well i have 2 kinds of feet so far (not shared yet) and a clean model without feet so you can put you own feet on them or make them wall mounted.
Right now im finishing a prototype of the wall mount versions with 72 ws2812b Diodes inside, will have a video up soon'ish, these will be on patreon only to start with cause this is not just design, MANY hours have gone into my bluetooth RGB system, also TDA7293 AMP will be there along other products, yes products as im building a platform with a lot of different things, next weeks ill be working on my lasertag rifles based on the lego chima sword, but with laser system, HUD, even more powerful sound and recoil

Also VERY big DIY 3D Printers based on my own printers that print these eggs, new printer is CoreXY as much bigger then my 2 printers will be hard on motor driving bed back and forth
(Old Picture a few changes have been made since)

Audio is not the best, but RGB versions of the Egg speakers (4") are getting there, only 2 patters in this video (split in the middle of video)

going to be 3 videos up soon (3 songs) to show the light system, have 18 patterns so far, still some tweaks to do, another demo video so far

I read on the Maker site that you use Tinkercad to design them and would very
much appreciate any tips on how to do shapes like these.
I'm interested in 3D printing mid and tweeter enclosures like those that sit on
top of the KEF 105 and BYW 801 for example.
