We’ve updated the design of this adapter.
A shoulder portion was added to prevent the adapter from threading in too far. (This could cause the LipSync housing to crack due to the tapered threads.) We also added a hex portion to make it easier to install and remove. A 24 mm wrench, crescent wrench, or slip-joint pliers can be used to help grip the mounting adapter now.
The print and design files have been uploaded to Thingiverse: https://www.thingiverse.com/thing:3192305
Let us know how well it works, or if you have ideas for improvement.
