KLP1 runout sensor

This object is meant to fix filament tube and to move the runout sensor to a more sensible place.

The filament tube is fixed, so you do not need three hands to load filament anymore - now you can push the filament into the runout sensor and hold the filament lever on the print head open at the same time :-)

The runout sensor is moved to a place, where it is closer to the center of a filament spool and a little further away from the spool.

Printed in PLA, 0.2mm, 15% infill.
