DIY Part Fitment/Installation/Wiring

This is a universal DIY 3D printer part. That means it will work on almost any 3D printer, but you must know what you are doing.

Our technical support does not cover selecting/designing/assisting in firmware setup and/or 3d models to install this part on your printer. If purchased as part of a kit from TH3D for a particular printer, then it will be covered under the kit when using our firmware package.

Electrical replacement parts usually will require you to splice wires into your existing ones for the part you are replacing (soldering and heat shrinking wire splices is recommended for proper connection).

Some of our universal electrical parts come with bare wire ends or plugs on them. These ends may or may not directly plug into your 3D printer. If they do not, you will need to splice the wires into the existing ones on your 3D printer.
