I Wantet do add whatever symbol or text to my Hard Hat even with the ear protectors mounted. And now you can as well :D

The holder can hold a product that is 5mm thick, but if you like to have thicker things in there lett me know and I'll upgrade it for you.

Se picture if you need guidance.

Remember: This is a Beta version of the product and might have some flaws, that I will sort out during the test time at work this week. More pictures will come as well
