cute!

very handy, even works in several other brands’ spools

works great, super loud!

It was fast, cheap, and good! I made a mirrored version as well, just ‘cause. This mechanism works the smoothest when you are pushing “in” (closing/hiding an option’s switch pushes the other two fully open/visible); I’m curious if there is a simple way to design it in the other direction: “opening” or pushing out a switch forces one of the other two back in.

printed great, works great!

They all seem to work fine in PETG, even the looser ones are still snug enough to stay clipped onto the filament I have, so I printed a couple of each size and just chucked them all into the drawer and should be covered.
