Support for macon ruler

Support for my macon rulerIt allows to store my macon ruler efficiently in my garage. Convenient for ruler with width=10cm and height=2cmTwo or three of these supports are necessary, depending on the length of the ruler (I used 3 supports for my 1.5m ruler) Can be printed without any support. I've printed them in PLA (my ruler is in aluminium, so it doesn't weight too much)
