Because I want to use the AudioMoth where "removal" is an issue. I'm looking at the Samson 1 Micro case, my idea is to alter the foam to hold the AudioMoth and drill a hole for the Microphone and cover the hole with clingfilm. I can then use a padlock to close the case and lock it onto cyclelock/python lock. The case I'm getting is scuffed hence the cost of £15 inc postage. I did look at the ePTFE stickers for the audio windows but they only come packed in 1,000 which is too expensive for me. If anyone has advice, please chip in.
