CR-10 Z endstop filament sensor

(change notes)

V.2 added smoother filament passtrough which should work better
added handle to the lid for easier opening

When switching over to a bed leveling probe I figured I could use my stock Z axis endstop for a improvised filament runout sensor.
I modified OneMake's design by adding a lid and 2 bowden couplers to it, here's a link to OneMake's original thing: https://www.thingiverse.com/thing:2462029

Things you need:

A creality endstop (works with CR-10(s), might be compatible with other creality machines)
1x M3x35 countersunk screw (for mounting the lid to the housing)
2x M3x10 screw (for mounting the endstop to the housing)
3x M3 nut
2x 4mm bouwden coupler M10

After assembly the filament sensor can be inserter in front of the extruder.

Here is a video of Chris Riley explaining how to install and setup the plugin in octoprint:
