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.
