Use to hold the USB power cable into a SPOT trace unit. Uses the original fasteners. Designed for a Samsung-style USB connector end. Solidworks file included, so you can mod for other connector sizes.Suggest building with the cable exit side down on the print bed. I used supports in the 2 screw bores - they were difficult to remove - maybe try to print without support and see what happens. Those faces need to be flat for the proper screw depth, so be careful. Minor touch-ups are expected to get everything just perfect - as usual... Only printed 1, and it came out really good - with a nice firm grip that should do well protecting the USB cable from damage. .STL file should be in millimeters.
