This adapter can be used to mount a ABUS Smiley 3.0 LED Light on a non Smiley 3.0 Helmet. I glued it on the helmet using a doublesided sticky foam from an Aqara Window sensor. A sticky tape made of foam helps to cover the (not perfectly matching) konvex surface of the helmet.
For printing, any material should work. Please make sure to print it on its side and definitely use a brim.
Safe cycling to everyone!
