Making a Digital Thermometer for your 3D Printer

This is a 3D printed thermometer I designed for measuring temperatures on my 3D printer, such as the bed, power supply, hot end, and more. If you like this build, subscribe to Desktop inventions for more projects in the future!

The wiring diagram helps out so much, thanks!

[@DesktopInventions]

You're welcome! It is a lot of wires to keep straight!

[@Jim_One-wl4ke]

Yeah cool.👍.that’s what I need. Can’t find any vid showing heatbreak temp. This could probably let us know how much we could push the hotend so the heatbreak designS really can retain the filament solid state so the extruder works well. Thanks for sharing ❤

[@Vette0804]

Found it! haha

[@dury10]

Cool little idea! Can you do this using a raspberry pi?

[@DesktopInventions]

Yes a raspberry pie should be capable to read thermocouples and output the display, but the form factor might be different. It might not fit in the same 3D printer case.
