Hey man.
Just wanted to say thanks. I printed the part a month after you made the model. It just snapped. Thats about 3 years of heavy use. So printed a new one this time in Polycarbonate blue fillament. So thanks for the model. Keep up the nice work :D if you have a way of giving a cup of coffee or something please let me know :D
Best regards

Hi :),
could you please upload also the original designe files?
I like to add/change some parts, but with the STL file its quiet hard to do a good new designe.

with best regards Ripper121 (ripper121@gmail.com)

Hey Ripper 121,

I just uploaded all the files I had lying around on my computer.
I run a mac with Bootcamp Windows so I didn't check if it's the Solidworks files that you need. Nowadays I try to model more in Fusion 360.
Let me know which ones are useful and which ones I can remove from this thing page.


Would be nice if you can leave them all. (if this is no problem for you)

Thank you a lot gaspardbos, you just preserved my TMA-1 from to going to the happy hunting ground.
I printed the headband with PETG with 100% infill and it is feeling perfectly on my head.

I decided to glue the rubber band just under the AIAIAI writing. It feels more comfortable to get the full contact of the rubber band on my skull.

Hey ThePeacemaker,

I did exactly the same thing; glued the rubber part back in.
For people who lost the rubber part or who want to modify it it could be an idea to model it and reprint it in Ninjaflex or a similar thermoplastic rubber.


Printed two in PLA, 100% infill, 0.2 and after a couple weeks it breaks in the same place as the original headband. Any advice?

Maybe try a different filament brand? Some PLA filaments can be very UV sensitive and prone to degeneration, hence they become more brittle.

hi thanks for this, which material do you suggest for printing? i mean for the weight and resistance.
thanks in advance

sorry, didn't catch your comment in time.
I printed one with white PLA at about 85% and it has lasted thus far.

What should i do to change the piece?
Many thanks.

Hey Ic99, read the description in Thing Details. You can remove the earcups and the rubber band from the original plastic headband piece and then glue back the rubber band on the new 3d printed headband with which you also put the wires from the earcups back in place.
