Geoffs Nozzle Size Indicator

thingiverse

With multiple 3D printers on hand, keeping track of nozzle sizes for each one can be quite challenging - numerous examples exist online, but I sought a solution that was both easy to read and difficult to alter accidentally.\r\n\r\nI printed mine in two distinct colors (layer change at 22 with a 0.3mm nozzle), although a marker or texta color would also suffice. Upon completion, I ran a 3mm taper tap halfway through each hole - the indicator is an M3 screw, which could be replaced by any small screw suitable for the task.
