If you want to mount your filament spool on the side of the K1C, you are still left with the runout sensor and the feeding of the filament at a very bad place, still on the back close to the printer. So I designed this very simple bracket as a side mount for the runout sensor. So that the end of the Bowden tube is now easily accessible from the front/side of the printer. The design is made the mount at an angle so that the natural line points to the middle of the spool, so that there will be less drag on the side of the spool, but at simple straight flow, and i also reduced the bends in the Bowden tube. This file should have been included on the USB stick for the printer.
