Today I learned you can buy an explosive fire extinguisher for your 3D printer.
The Wham Bam Cloud Personal Printer Sentry is a $29 gadget designed to protect your home if your printer catches fire, by exploding into a cloud of extinguishing powder if direct flame touches it for 2-3 seconds.
Most reputable 3D printers have thermal runaway detection; I don’t know if it works in practice; insert lp0 joke! Totally just bought one anyhow.
