Another filament sensor! This is an extremely small filament sensor that uses an Omron micro switch and a 5.5mm ball bearing, prints completely without supports and inspired by best shape found in nature. It uses 2 ECAS fittings and is designed to connect in line in any PTFE tubing wherever you want. It's so light no mounts are really needed however there are 2 spots for brass inserts if you decide you do want to mount it. 

 

There are two versions, the JST version which has a little spot to mount a JST plug if you want this thing quickly removable, or one without where you are expected to solder your wires directly to the Omron switch.
