When I take the windscreen off my trike, I loose the storage bag that is attached to it. I've lost 3 pair of glasses, hanging from my shirt collar, because I didn't have a handy place to put my reading glasses. Now I do. Stick a cheap foam/cloth glasses soft case in it, and it doesn't rattle. Not that I'd hear a rattle on my bike.

Should fit any 1" tube... in my case, Harley Davidson factory 1" bars.

Print with bottom of box down... model wasn't created that way, so you might have to turn it. Organic/tree supports on to get the screw mount printed cleanly. I embossed my name on the front, which is why there is no vent slot on that side. Knurled retaining nut doesn't need supports.
