Every altimeter installation I've seen mounts the altimeter rigidly to some part of the rocket--an AV bay sled, a nosecone, between fins behind a hatch, etc. For altimeters that rely on inertial measurements (accelerometers, "tiltometers," etc.) this is paramount. I wonder about non-rigid installation for purely barometric altimeters.
I'm imagining an AV bay that has screw-on caps on both ends and terminal blocks with requisite wiring. I connect the altimeter as necessary and then wrap it in an old t-shirt or a sock and stuff it into the AV bay. Then I screw the cap on, and I'm ready to go. The fabric holds my electronics securely, lets air pressure pass through and provides a measure of shock absorption in a hard landing.
As I've not seen anyone do this, I wonder if people have found out this idea is problematic somehow.
