Description
⚒ No 3D printer? No time to source components?
I just opened my new e-shop where you can buy physical, ready-to-use versions of my models! Designed with passion, printed and assembled with care ⚙.

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 !
