Phone/Ipod/Camera/Identification Armband Holder (Mulbarton NR14)

Anyone got an old usable armband holder capable of taking a camera 8cm x 12cm x 8mm thick?

Trying to get my own cyclist dash cam kit together to mount my iphone /ipod shaped camera to record my trips. Had found an armband holder but it was too old and glue disintegrated. Looking for any method to securely attach camera to person or bike to log my trips.

Hence armband identification holder or (more rare) actual screw mounted camera holder??

Thanks for looking.
