Key fob for roof bars lock

A fob to make it easier to find the key for lockable roof bars in the under-floor stowage in my car. I thought it would be fun to have a fob which was made just from letters rather than being embossed on a flat surface.

These roof bars need an Allen key to fix them in place. keytag3.stl is a modified version with loops to hold the Allen key, in order to keep everything together.
