Have you ever cut your finger, or splice some wire there, well I come to the rescue! (ok neither of which happened to me, but always kinda bothered me how sharp it was)
Well not much else about it, beside being a snap in place.
Print in PETG preferably (or anything that doesn't snap and break easily) , as it needs to bend tiny bit to install it, and PLA might snap in half (but feel free to try, chances are it will still work fine.)
cheers!
