Bambu Hot End Wrench

Many manufacturers make hot ends for Bambu Labs printers that feature replaceable nozzles. Most of them come with a stamped sheet metal wrench to screw the nozzle into the heater block, but the problem I found with mine is the heater block is only held into the heat sink with grub screws, so it just spun around. My solution? A quick and dirty wrench that fits perfectly over the heater block without having to remove the ceramic heater or its clip. Just slip it on the edge of the heater block, and you can hold it still as you remove or tighten the nozzle. Enjoy!
