Remixed from ‘Ender 3 Pro - PSU Offset Mount (dual z-axis)’ by emtrax to work with the stock Ender 3 PSU by Cheng Liang
This remix retools emtrax’s super slick, ultra functional Meanwell PSU mount to work with the stock Ender 3 power supply which is wider, has different screw positions and requires a cable conduit through the base of the mount.
Another functional and aesthetic addition in this remix is an optional printable 4040 extrusion extension that can be seamlessly attached under the mount overhang with 2x 75mm M5 machine screws into the end of the existing frame extrusion. This provides a tidy, concealed conduit for both a PSU ground wire** direct to the printer frame and a clean exit channel for the PSU connection cables that feed through the base of the mount. When installed, together with the mount, the 4040 base extension creates a seamless super-clean look without the typical PSU over-hang that reveals an obvious relocation. The extrusion extension also adds extra realestate for clip-in cable management options like this cool simple solution by J-Max: https://www.thingiverse.com/thing:2666871
See included images for recommended print orientation of parts with minimal tree supports using an overhang angle of 70deg.
Installation should be pretty straight forward and hopefully all the included photos help, but incase anyone gets stuck, here’s a detailed step by step guide:
** Removing the two screws that secure the Ender 3 power supply to the frame in its factory mounted position inadvertently severs the ‘earth’ or ‘ground’ connection between the PSU and frame. It’s important to restore this connection during the relocation process by running a simple and easy ground wire from the back of the PSU case to the raw metal end of the base frame extrusion. See required hardware list below (very inexpensive) and build photos to see how easy it is to do - just strip a little off each end of the wire, twist the loose wires a little so they’re easy to insert into the terminals (you can tin with a soldering iron if you want, but not entirely necessary). Slide wire ends into the terminals and crimp tight. If you don’t have a crimper you can get by squeezing firmly with a pair of pliers, then placing a flat head screw driver along the plier-flattened part of the connector and tapping with a hammer a couple of times for deeper, firmer crimp.
Hardware required:
2x 8mm M4 machine screws (for securing the mount with t-nuts)
2x M4 t-nuts
2x 75mm M5 machine screws (to attached 4040 profile extension)
1x 6mm M4 machine screw (to attach ground wire to PSU)
1x 8mm M5 machine screw (to attached ground wire to printer frame)
1x 8mm M4 machine screw (to attach the front end of the PSU to the new mount)
**30cm of 14-18AWG electrical hookup wire (for ground wire)
**2x Fork or ring shaped electrical terminals (to crimp to each end of the ground wire)
