The new Prusa case comes without a fire extinguisher, but I think it's a good idea to install a smoke detector and fire extinguisher directly into the case, especially if you're not always watching the printer.

I used the "Fire Cookie” from "Brandwächter24" for my Prusa enclosure. This system is suitable for 0.3 square meters of room volume and is activated by a fire (flames).
The holder consists of 4 parts (holder A, holder B, connector, safety plate).

Place the "fire cookie" in the two holders (A and B), connect the holders with the connector and secure it with the safety plate (use the opening in the Prusa enclousure).

You need two 3mm screws and two nuts (place the nuts into the connector) to fix the connector to the enclousure. With two additional screws (3 mm) you can secure the holder A with the enclousure (use the existing holes in the plate)

I will add some pictures to explain the construction.

I have designed the parts with FUSION 360 and used some support material for the connector).

I have never tested the function of the extinguisher but I hope it will work in the case I need the system.
