SummaryI had seen some jerry rigged hula hoop mounts and thought I could make a more official looking one. I collaborated with a hula hooper I know for various dimensions. This mount is designed for a 3/4" minor diameter and 33" major diameter hoop. I eventually will make a shim for smaller minor diameter hoops. I don't have a hula hoop or know anyone near me that hula hoops, so please make and test this thing!Print SettingsPrinter Brand: 3D SystemsPrinter: CubeProRafts: NoSupports: YesResolution: Something around .2 would be fine, that's what I usedInfill: Shouldn't be super low, between 20% and 40% would be fineNotes: Should only need support for the portion of cylinder on the larger piece, maybe for the holes or the hex nut holes, I didn't.Post-PrintingThere are three places for captive nuts, two are pretty necessary and the third isn't as important (it's on the part the GoPro actually mounts on). The two to secure it on the hula hoop are 4-40 hex nuts (http://www.mcmaster.com/#90480a005/=10ap1ln) and should be mated with two 4-40 .5 " pan head machine screws (http://www.mcmaster.com/#91772a110/=10ap3cb).
