We keep losing caps for our Zoom! This easy-and-fast printable replacement cover is a near-identical replacement for the stock covers that come with the module.
...Plus It's a snug fit, but it's working well for us.
It also says 'Cool!' in the bottom, to remind you to stay cool on-set. If you're not a fan of that, I'll upload another version without it when I get around to uploading pictures of it.
This part pairs nicely with the cover for the Zoom itself: https://www.thingiverse.com/thing:2337123
