This is a simple hula hoop holder I designed for my girlfriend, it is designed to allow you to set the top one without any resistance, and the bottom one you put at an angle to easily slot in, then when it sits straight it locks it into place. It is designed to fit 2, 35 in diameter hula hoops that are about 1 inch wide. It has the weird lines in it because my printer has a mechanical issue that I am working on fixing
