My daugther and I built a Wheel of Fortune this week-end. Here is the design of the arrow that acts as the pointer (see picture).
- start with a picture search
- modify the picture with Gimp so as to have only one half (file arrow.png)
- open the PNG with Inkscape and draw a path that follow the outline of the arrow
- deepen the notches in order to make them more visible
- use the Inkscape extension Generate From Path>Paths to OpenSCAD to turn it to an Openscad design (3mm height)
