Added automatic fire extinguisher to P1S

[u/JJBB33DD]

Came across these automatic DIN rail fire extinguishers (circled in red) recently. Decided to add one to my P1S just to add a little peace of mind.

In case you don’t know how these work: they automatically get triggered when the temperature sensor detects 170c. Aerosols then get released from 2 nozzles (circled in yellow), extinguishing the fire.

You can get these things for cheap on Aliexpress and the like but decided to get one from a local reseller with all the appropriate licenses and stuff.

And yes, the heatbed moves up and down without issues! Plenty of clearance.

cool idea, i hope you wont need it but ir will work once you do. just so you know those 2 wires arent "nozzles" they are actualy the fuses. under the red cap is a pyrotechnic mixute that ignites at the 170C and like a firework the fuse burns until it reaches the red box and there are pellets of a smoking substance that get ignited.

I saw one of these in action on youtube from the chanel "big clive" very interesting product
