Excited to see so many peppers growing in our tiny window garden. Thanks @quixoticgeek for the plants!

Our FDM printer had gotten extremely loud, and I thought I needed to replace the bearings or something. Just putting some foam under it was enough to reduce it ~15dBA, and now I can hear the raindrops outside again.
