Quick and easy print to store your shiny new E3D Revo nozzles, I used small 6mm x 3mm magnets held in with a drop of superglue, which allows positioning in several points on the outer printer case. If you're a real perfectionist, use the text editor in BambuStudio to add a label for your specific nozzle sizes! PETg, ASA and PLA all print well and work, no need for high-temp material as this is outside of the print enclosure.
