USB Strain Relief Rev Expansion Hub - Universal

thingiverse

Works with many standard straight and 90-degree mini USB plugs. Take the stress off your mini USB by tightening a few bolts and securing zip-ties. I suggest attaching the REV module to your robot using Velcro, then sliding pan head bolts up through the bottom of the rev module, up through the relief model and fastening with nuts. Insert your USB plug and wrap zip-ties around it. In some cases, the 90-degree plug will be too large to fit snugly in the two slots located just left and right of the plug. If that's the case, I've added additional slots about an inch from the middle on both sides, depending on whether your robot's design bends to the left or right. To secure it, simply wrap a zip-tie around the cable of the 90-degree plug on either of the outer slots. Although this may not be as secure as wrapping it around the plug itself, it is much better than nothing and we've never had one come unplugged.
