MASM 7

Had a real hard time getting everything to fit... even had to 3D print the RAB resonator and a 90 degree angle for the BS6.

@dhruvmeena96 you're right about the amount of detail on this thing! My hats of to you for the design!

The real magic happens when you feed power with a super clean amp(real ground amp) and a good DAC.

MASM 7 requires power to shine, even though its low impedance and easy to run anywhere...with its dB.

I am using THX AAA789

For anyone looking to print a shell, try this one, modelled after KZ ZS10 Pro

The nozzle has 6mm OD, 4,3mm ID (hope u can put 2 tubes inside)

This stuff is absolutely Awesome!

Can you do a faceplate for this one too?

Also, do you think you could construct the nozzle along these lines:

but maybe a variant for x2 2mm ID (3mm OD) and maybe x1 2mm ID (3mm OD) and x2 1mm ID (2mm OD) tubing, if its no too much trouble?

Awesome! I've tried printing some shells from Thingiverse.com free designs, but none were usable.

From my experience I know KZ ZS10 is a bit bulky. Did you make a bit smaller shell?

I do the same thing but old style - simply carefully seal the earphone I want to copy and pour agar agar over it. Then I can make a first set which is usually not the smoothest one, sand it, adjust it, then make another negative copy with agar agar and I have a perfect negative form for future use. My preference is a bit modified KZ ZSR shell, it is very close to Ibasso IT04. Most comfortable and most secure fit in the ear. I also used KZ ZST (for double CI+TWFK since it would not fit into ZSR shell) and some generic Shure knock offs from Ali that I plan on using for one driver setup (when I find the one I like).

Yes it's bulky compared to shure shells, and mine's even a bit bulkier, :)

Its gonna be a challenge to model zsr shell, it has nooks and cranny everywhere.

Gonna try when i get my hand on one of the zsr.

Bulky is good, especially if doing hybrids or multi-drivers especially helpful to keep tubing straight.
Well, as long as the shell is not falling out under its ow weight...

Bulky is good until it can fit in your ear. Otherwise it is unusable :)
ZSR has a bend in the middle and it is using a lot of space. But as for now I couldn't fit only 2xCI + TWFK with a lot of wiring and components (piotrus-g 3 way design). All the other fit without any problem - ED+FED, GQ+RAB, GK+RAB, BS6+zobel.

4.3mm ID

Its more than enough for 3 tubes of 1mm ID...


I am still thinking of something with BK.

I hate drivers having peak at 1kHz(at any dB).

But I have heard some BK bass... And it sounds tight and punchy...if tuned properly
