"Open Alpha" T50 3D printed headphone project from MrSpeakers
Oct 9, 2022 at 10:53 AM Post #856 of 979
I'm confused about parts and construction if someone can help me please. I have printed the two part baffles and cups. I still need:

- 2.5mm headphone jacks. Would these work? https://uk.farnell.com/multicomp-pro/mj-165h/socket-2-5mm-jack-2pole-pk2/dp/1267391

- Sound damping foam - Akasa paxmate is mentoned which is 4mm think, it is quite expensive, anyone got a cheaper alternative? Could you use a cheap mousemat for example?

- Some kind of "wool felt" or "closed cell foam" to surround the baffle on the ear side - anyone got a recommendation for this? Can the same material be used as the foam above?

- "Soft closed cell foam" to make a gasket, any recommendations? i don't want to use silicone!

Are those the main parts required apart from earpads and cables? Did I miss anything?


Thanks for any help!
You need jacks where the nut is on the jack side and not the tab side; you wouldn't be able to secure the ones you linked.

Thank you! The pictures really does not do them justice. Its a special color plastic that was used to print them. In sunlight it turs coral green, looks stunning when you have them in hand and turn them towards the light.
You can kind of tell from the picture that there is something special about the color... The green specks in the last pic :)
Very cool. What finish did you apply? I am printing mine in two colour pink and blue silk filament, but don't know if I should leave them raw, or try and sand or apply some lacquer. What did you do as yours look excellent? Thanks.

Hi all,
I've been excited to do this project and I am familiar with CAD, so I have made some modifications to the original design to use threaded inserts, I haven't tested the design yet, but it is meant to use M2xOD3.2xH2.5 threaded inserts and M2x8 screws.
