My project is a DIY talkbox using Monacor KU-516 compression driver.
I'm having a hard time finding the right connector to fit the hose to the driver, M35 is a rare size it seems.
There's one option of M35 x 1.5 looking through the tables for metric-thread sizes.
There's no information on TPI threads per inch on the datasheet for the driver. I read a tutorial from another builder, he 3D printed a part with 18TPI and didn't fit perfectly.
If anyone knows any item I could buy to solve without 3D printing a custom please let me know. (I've searched tap/hose adapters with no luck)
If I have to 3D print a part how should I measure the TPI accurately to make the correct thread?
I'm assuming the 18 TPI fitting didn't work as 25.4 (1 inch) / 18 = 1.41
If the flange is M35 x 1.5, at 18TPI would the fitting not snug enough?
