UPDATE: Both brackets hove been updated. I incorporated a cap to the rear bracket that covers the frame extrusion and offsets the PSU backwards some.
These brackets will offset the power supply unit on a regular Ender 3, making room for a mechanically driven dual Z upgrade. Can be installed with four M4x8mm screws and T-nuts. Optionally you can just print the rear bracket as it's sturdy enough to hold the whole PSU. But using both will add extra support.
These are compatible with my Scuddy Dual Z Upgrade for the Ender 3 here:
Hatchbox TPU or PETG
Print flat side down. Use 20-30% infill.
Designed using Fusion 360 and open source Creality Ender 3 printer model.
