TeeBar v-slot filler
thingiverse
I made some for a Facebook poster who asked if they existed. They stop all the junk from falling into the V-Slot rail on my Ender-3... and probably many others too! The fillers are 140mm long, so they should fit easily under the Z rail. Just be careful not to push them in too far, or it's a real pain to get them back out.
