Original 0.24 nozzle doesn't have any dots marked on it.
V6
nozzles are designed for use with the E3D V6 heater block. Modify your
HotEnd to print with small nozzle orifices to achieve fine details or
larger nozzle orifice sizes for more substantial, stronger 3D prints.
1.75mm Brass V6 nozzles are fully compatible with several 3d printers.
Brass
nozzles, featuring E3D’s signature internal geometry, have optimal
thermal properties for everyday printing, providing smooth layers for
standard non-abrasive applications. Rated to a max temperature of 300°C.
V6 nozzles are designed for E3D V6 heating blocks with
23X11X16 dimensions, for example.
For replacing the nozzle on a 3D printer, a hex key can be used: a
7mm key.
Attention: - V6 nozzles are not compatible with Volcano, SuperVolcano, or Cyclops heating blocks, for example.
