I like hats. So the 1st thing I want to share with you is a customizable hat band clip with text and up to five feather holes. I like to cut off some 10 cm pieces of filament and insert them there. I've attached a black hat band clip to my gray hat. I printed it in black and gave it a rough sanding, so it looks like slate. I like to decorate it with transparent filament. You can change the colors of the "filament feather" in no time. I'll make another one for my favorite soccer team (BVB) with black and yellow feathers and another one with "Germany" on it, with black, red and yellow filament.Now it's up to you! I'd like to read about your hat band clip desings in the comments.All sizes are in millimeters. You can add up to five feather holes. For best print results use: 20% infill / 3 shellsBe careful when inserting filament into the clip: The holes have a slight angel, so it will look a little bit more streamlined.
