Hmmm, it might be a bit tricky, as I look at it. The wide end of the opening is just under 3/4" tapering down to 1/2".
There's room interior-wise ( 1 1/2" to 1".) But fitting it inside it could have to result in cutting the top of w/ a ultra-fine bladed jeweler's saw, inserting Bobo's unit, and gluing it back up. Not an especially imposing task...
That's really all I have to go with, Bobo, what's your measurements?
take care all,
