Saber coupler

The inner diametor bist du small for the speaker.

The threads on both sides are very good, but the inner diameter of the rest of the socket measures 21.7mm, but the speakers on Neopixel Sabers are 25,3mm. The rear cover of my saber has 25,5mm. More than enough for the speaker. In my work, I used a lathe to trim the inner diameter to 25,4mm. It's useful now.
