Spent $22 on a magnetic screwdriver and it saved me from losing a tiny standoff in the carpet
I dropped one of those little motherboard standoffs on my beige carpet in my Denver apartment and spent 10 minutes on my hands and knees with a flashlight before remembering the magnetic driver I bought on a whim for 22 bucks at the hardware store down the street. That little magnet grabbed it on the second try, which honestly felt like a magic trick at that point. What small tool purchase ended up saving your build night from turning into a total disaster?
