This is a (low tech) resistor calculator which can be used in electronics ingeneering class or for those who have trouble to read resistor color codes. It is dedicated to 4 band code (the most common).
You must print the resistance.svg file with inkscape on a color printer. Then you must laminate the paper, cut the treee disks and drill three 3 mm holes in the center of the disks.
You have now two options:
1) Cut and engrave the files fond.svg and fond1.svg files with a laser engraver. Glue the two disks and 3D print axe.stl. Use a M3x10 scew and nut for the axis.
2) 3D print the files axe.stl and axe150.stl and Use a M3x10 scew and nut for the axis.
