This is so simple I wasn't sure it was worth publishing, but I have found it useful, and it's a good way to use short bits of leftover filament.

I use these header pin covers to block header pins that I want to make sure I do not accidentally connect, so I don't end up with a bricked component. Of course I could always use a single pin dupont connector, but why waste those when I can just print out batch of these in an easy to spot color?

Two different lengths are provided, but of course you can always scale to get other lengths.
