A clean way to add a USB outlet to your printer. This is the MK4S version and allows you to power 5vDC USB items like cameras, etc., easily, without external power sources/supplies.
The unit requires the same parts as the MK4 version (link below) and you'll also possibly need some new, doubled sided adhesive, for the NFC card.
Printed with Polymaker PETG (black).
3 walls, 15% gyroid infill - a small support needed under the horizontal area of the converter mount.
***Use at your own risk and do not overload the converter.***

The author remixed this model.
The original part has been heavily modified to allow the use of a USB board mount and a converter to be mounted on the backside of the cover.
