Filament runout sensor small

Couldn't find a filament sensor for the size of micro switch I had laying around (size at bottom), they were all far too big.

So quickly made this one up.

I did make a cover for it which i have included and locates on small tabs but i never actually bothered printing it. I kinda like been able to see whats happening in there. but if you make it once it locates just glue it on.

Switch is friction fit but I made the hole at the bottom the size of a futaba connector as I wanted to be able to take it on and off, you could just wire in directly and have cables hanging out. I used hot glue to hold the connector.

Here is a link to a futaba extension, I just cut one like this and used both ends. (https://www.ebay.co.uk/itm/1-10-Servo-Extension-Male-to-Female-Lead-Wire-Cable-For-RC-Futaba-JR/192736103784?hash=item2cdff78d68:m:maQKD0zXCLcUJh7IZ2Mlftg )

The micro switch was ultra mini one body size 12.9mm x 6.5mm x 5.9mm using my calipers but pretty sure its the one in this lin
