David Clark Mic Adapter (Use M-77 mic on H10-76 headset)

My David-Clark aviation headset came with an old-school carbon mic (M-87) that made it tough to use with modern gear. So I bought an unamplified electret mic (M-77) from David-Clark and designed this adapter for it.

I opted to keep things simple - the mic mounts with a couple zip ties and a bit of double-stick tape. If it doesn't hold up I'll design a new one with a better mount. Seems to work fine so far.

Including the FreeCAD file. This is my first project using FreeCAD (I'm a Fusion 360 refugee, jumped ship now that AutoDesk is tightening the screws), so please forgive any odd design practices.
