Optical drive bay to hard drive bay sled or rails

SummaryUse this to fit a 3.5" hard drive into a half-height (5.25" optical drive) bay. I used dimensions from the following two standards: 3.5" disk drive: SFF-8301: ftp://ftp.seagate.com/pub/sff/SFF-8301.PDF 5.25" optical drive SFF-8851: ftp://ftp.seagate.com/sff/SFF-8551.PDF You can print either a full sled with a base plate, or just rails for the sides. If you use this, please feedback. Sorry about the messy code. InstructionsPrint out. Place 3.5" hard drive. Use 3.5 mm or #6 hard drive screws to affix to sled. The file is heavily commented, and comments like //A1 and //A14 refer to the dimensions given by the SFF-8301 and SFF-8851 standards mentioned in the top comment. Some variables of note include: $manifoldOverlap $screwRad $minWallThickness; $minScrewAllowance
