Prusa i3 USB Mount
Are you tired of fiddling with plugging in your USB cable? If you've mounted your electronics in the traditional location on a Prusa i3, chances are you have to navigate the bundle of extra wire behind your frame to do so. I know I've loathed that element of the single sheet design more than once.
Never fear though, I've got a solution! Note: It's not a new idea as several variations exist for older Prusa and similar printers.
Instead of contorting your hands or leaving your USB cable attached permanently, use my USB relocator!
This thing uses a USB Female panel mount to Male cable to relocate the USB connector to the front of the printer. See photos.
