USB-B Connector Shell

thingiverse

Simple USB-B connector shell for use with replacement USB-B connectors. Background: I rely on the Arduino UNO for numerous projects and opt to provide power via a regulated 5V power supply through the USB connector, bypassing the thermally challenged onboard regulator and ensuring over-current protection. Therefore, I find affordable (or handy scrap box) 5V power adapters, shorten the cable to the desired length, and attach a USB-B connector. To complete this setup, I designed this simple slip-over cover for the connectors, which were inexpensive but lacked a shell. If you also have a collection of bare USB-B connectors, here is a shell that can dress them up. Print Settings: Printer: Modified XYZPrinting Da Vinci 1.0 Rafts: No Supports: No Resolution: .2mm Infill: 10% Notes: I used ABS because it's tough and somewhat flexible. These shells simply press-fit over the connectors, requiring no glue. They print upright with the back (cable end) facing down, necessitating neither rafts nor supports. Your results may differ; you could likely use PLA but might need to scale it slightly as it is stiffer than ABS.
