Adjustable Nozzle Indicator for most common nozzle sizes 0.2 0.4 0.6 and 0.8

If you often change the nozzle in your printer, or if you have several printers with different nozzle diameters, this nozzle indicator will come in handy. By turning the wheel, you set the dial according to the nozzle size you have currently installed in the printer and it clicks on fixed positions. 

Prints easy and fast - apart from the STL models, also print profiles for BL A1 are included. Once printed, a small drop of glue keeps the parts together. Can be attached to flat surface using double side tape.
