Filament Out Side On Sensor box Button Microswitch

It is designed to have the filament feeding through from the sides.

Underside fitting of pnuematic passthrough fitting.

There is a "Not_10mm_Body_Filament_Out_Side_On_Sensor_box_Button_Microswitch.stl" which has no 10mm Boden fitting threads

This is for use with a microswitch with a lever arm. It is used to detect if the Filament has run out/snapped, etc..

With the previous version Filament Out Side On Sensor box Microswitch it was a bit awkward to re-feed filament.

The lid generally needed removing and the filament need to be feed back through the hole in this lid and the over the top of the microswitch arm and then out through the other side.

With this Improved "Button" Version there is a button to press that pushes the lever on the mocroswitch so that the filament can be passed over the top of this microswith lever arm.

I have also added some chamfer to aid feeding the filament.

This is 3D printed quite thin plastic.

I class this as iteration One improvements may follow I suggest:-

I am making untested:=
Filament Runout Sensors Optical Side on Filament feed.

It is for use with Marlin :-
FILAMENT_RUNOUT_SENSOR : Note ADVANCED_PAUSE_FEATURE is required in Configuration_adv.h to use M600 with FILAMENT_RUNOUT_SENSOR

and for connetion of the microswith to the RAMPS 1.4 board

NOTE : set Unload filament in Marlin etc. to zero, feeding filament backwards into this will cause issues.

Has a part 10mm thread for fitting to a Bowden fitting

Both main parts have 2.5mm holes for screwing 3mm bolts into for mountng.

There is a Lid with a bit bigger edge so it is easier to grip and open the box for fitting, etc..:-
May need filing a bit
