Frequently asked questions
Which hotends does this nozzle fit?
It is listed for MK7 and MK8 style extruders. Confirm the thread and seat on your hotend before installing it.
When should I use a 0.3 mm nozzle?
Use it for fine detail, thin walls and small features. Expect slower prints and a higher risk of clogging with abrasive or dirty filament, and adjust the slicer settings to match the nozzle.
