Dual needle gauge

After I have built my first single needle gauges I now made a next step forward to the "Duct Pressure Gauge" - a dual needle gauge. This time with the help of my laser I was able to design some filigrane needles and angraved and filled them with the wax method. This gauge will be part of my pneumatic system panel.

Materials used:

  • 3mm clear and white acrylic
  • 4mm acrylic shaft
  • 7mm acrylic tube
  • 2 servo motors
  • 4 female and male hex standoffs
  • LED stripes for backlighting

In the download package you will find all the files you need to cut out all the needed acrylic parts at home.
