Universal Direct Drive Mount

his mount is designed for any printer that uses a 2020 aluminum extrusion for the X‑carriage, including Ender‑3 variants and most Creality‑style machines. The goal was to make a direct‑drive setup that installs cleanly without special hardware or custom brackets.

The mount holds a compact NEMA 17 extruder and keeps the weight close to the rail for better print quality. All the screw locations are easy to reach, and the design uses standard M3 hardware and 2020 T‑nuts you likely already have. If you want cleaner cable routing, you can run the extruder motor with a simple stepper extension cable.

This is a solid option if you want to switch from Bowden to direct drive without rebuilding your whole carriage. It’s straightforward, rigid, and works across multiple Ender‑3‑style machines.
