You can get Hair Bands in various styles and materials more or less precious but with a 3D Printer you can print one exactly adapted to your Head.
Ask your girlfriend/wife/daughter for the prefered color. You will be suprised about the answer you get. Just print several Hair Bands in different colors :-)
Customize the Hair Band as you need.
A partial brim is added at the ends to stick down the print.
If you prefer others printing techniques, set "Partial Brim" to "No".
