Give your model to a reddit bot and let it loose on /r/me_irl.
There are plenty of subreddits and online forums where a single-purpose lightweight CNN like this one could be enormously productive. It would obviously need a small backend somewhere, but the hardware requirements are minimal.
Something to automatically help users identify forum-specific images (e.g. poisonous/harmless spiders, bedbugs/beetles, snakes, etc.) would be useful, and the network would be the same.
