As a hobby I have started 3d printing and swapping out some parts of some old DT770s including cans and headband/ yoke.
The cans have been working out pretty well,
I am printing the headband now to try it out (it is designed to fit my head)
Long time reader here but first time posting some of my handiwork hehe
here is a link to download my headband file if anyone wants to play around with it:
