Nozzle Indicator

A small, intuitive gauge displays the current nozzle size. I sought a compact indicator smaller than UltiArjan's Dial version, one that also shows the size and material - Brass or Stainless steel - of the nozzle. Two versions of the holder are available: A clip-on design attaches to the UM2's front left edge; for right-hand placement, mirror the part in your slicer. This version can be printed with 0.8mm walls and 20% infill. Alternatively, a plain holder adheres to any machine surface using glue, double-sided tape, Blue Tac, or another chosen method. Print two discs in the desired material color; I used ColorFabb PLA's "Bling Bling Gold" and "Robot Silver." These colors are available by the meter from various suppliers. To create the gauge, print 100% infill discs and then mark them with a fine black marker pen, filling in the text and numbers. Attach these two discs back-to-back. Simply insert the disc into the holder, with the side and nozzle size of choice visible from the front; this disc includes available nozzle sizes from e3d-Online and 3dSolex.
