Connects your 5mm motor shaft to 8mm threaded rod so your Z-axis moves straight and true
Allows slight angle shifts if your rod bends, so your printer keeps working without damage
Open-source design means you customize it to fit your exact setup
Print on demand; get the part you need without long waits

Your Prusa printer's Z-axis needs parts that work together perfectly. This coupling joins your motor shaft to the threaded rod while staying coaxial, so your print bed moves up and down smoothly. Even if your rod is not perfectly straight, this part flexes just enough to keep things running.

The coupling pairs a 5mm motor shaft with an 8mm threaded rod. It holds them aligned so they spin as one unit, yet allows a bit of angular movement. You get reliable Z-axis motion without binding or wobble. The design comes from nophead's open-source work, tested and proven by the RepRap and Prusa community.

Order this print-on-demand part and receive it ready to install on your Prusa printer. No long supply chains; no waiting weeks. Just the part you need, printed fresh.
