Parametric Bicycle Compass Mount

Parametric mount for mounting a compass on your handlebars or frame.

I've also provided a lid which indicates the direction the bike is pointing - for this to work, the compass should be oriented toward true north, and the lid should be oriented with N pointing forward. Thus, when you are facing north, the compass and lid will both point to the north. When you turn right, the compass will indicate that north is now to your west, and the lid will indicate that you're travelling east.
