General motorcycle blinker adapter

This is an adapter for the motorcycle blinker.
On some motorcycles (like mine Triumph) the blinker are mounted with M6 screw and an additional hole for the cables. Most of the aftermarket blinker comes with a M8 screw and cables pass trough the screw.
With this adapter you can mount M8 threaded blinker on a M6 threaded motorcycle.
I've not road tested the adapter, try at your own risk. I suggest to print it with high resistance material (such as ABS) with 100% infill.
