If you have a Honeywell alarm keyfob like the one pictured, you'll know how easy it is to accidentally press the buttons. This cover slides on and protects the fob from accidental activation.
I printed in on my AnkerMake M5 and it is a snug fit but slides on & off easily. I printed it upside down (largest flat surface on the bed).
