Fuse access panel on my S3 keeps dropping down

The fuse access panel on my S3 keeps dropping down into the passenger footwell. It's more annoying than anything else, but eventually something will get damaged. I've tried velcro, but that didn't last long. Has anyone got a simple solution that doesn't involve moving some of the electrics to a new location?

Thanks for all the ideas
