I know many here use the
Cigar Caddy cases to store their pencil mics. I have been using one for quite a while, but since my mics are really tiny, I wanted to protect them further from knocking into each other during transport. I almost bought some of the
Schoeps twist vials made for CMC bodies, but $6 each plus shipping seemed a bit too high for something so cheap to make.
Instead, I found
these tiny versions for dirt cheap, and they are perfect size to hold the X-Qs (51mm long). I tried using them with the CM3s though (77mm long), and they are just barely too short for the threads to engage. A user on GS recommended McMaster-Carr, and sure enough, they have their own version. See "Adjustable-Length Plastic Tubes"
here. I bought the smallest size of the 0.79" dia tubes (just over 20mm ID), which as you can see hold the CM3s perfectly with room for a silica gel cylinder in there. If you have mics that are more normally-sized, you'd probably want the medium length. The plastic is a different, harder type than the CountyComm versions (which are closer to the type Schoeps uses), but they work the same.
