This helps you protect your 3d printer nozzle while you work on your printer (i.e removing extruder, changing bearings, etc) it helps to stop the nozzle from hitting the print bed or other components on your 3d printer, it's also really handy to protect the ruby nozzle.

Note: Print has a small hole to attach a keyring, string or label/tag to remind you to remove the cover before printing (like on planes “remove before flight”) also this has been tested to fit on a 0.4mm nozzle size and add crush rubs but this may too much detail to print

Print Settings:

• Any Layer height
• Any filaments types
• No supports required

Have Fun :)
