I designed this small device to be able to alert me in the unfortunate event the nozzle clogs. It does so by monitoring the flow of the filament

This small device allows you to detect if the nozzle of your 3D printer clogs at any time while it’s running. Jamming does not happen very often but when you are printing large parts it can really save you a lot of time to be alerted as quick as possible. It is attached to the top of the extruder using double-side tape and it is connected to the 12 V DC rail of the hotend fan. I printed mine in ABS to prevent deformation of some parts due to heat since my Prusa is enclosed.”
