I wanted to know if my main heater was ON or OFF quickly, and also which radiator valve was active or not. Also I like these filament that change color with temperature.

So here it is, the Radiator Visual ON/OFF Indicator using thermal filament.

• No support needed when printed at 0.1mm layer
• No MMU needed, just change the filament twice (or more !) to create the desired pattern
• Easy to install, just clip it on the standard 30mm connection/screw, (see last picture).
• Color changes will depend on you filament, I used on of these “magma” filament from dark green/grey to orange/yellow.

First time I use a thermal filament in a non-gadget project.

Hope it helps !
