Simple cap mount with an angle of 12° that can be mounted on the upside or downside of your cap. I just like the downside version because it gives me a view on the buttons and leds.

Simply drill 8 holes through your cap (use the iron solder to drill is a lot better, won't destroy the tissue)

Just tie everything together... et voilà!

If needed, ask me for other angles (.ipt and .dwg in the files)
