This modification reinforces not only the Z-axis against the right aluminum profile but also against the entire frame. A reinforcement limited to a single profile does not prevent it from still rotating within the front and back plates.
The base plate is available as a DXF file for production on a CNC milling machine. The 3MF file can, of course, be printed to have a physical model in hand. However, for the actual assembly, I do not recommend this, as the required rigidity cannot be achieved in this way.
The AngleV3 has two grooves milled into the back: one to accommodate the slight protrusion of the original Prusa aluminum plate and a short groove to provide space for the screw head of the Z-extrusion.
If you plan to undertake this modification, I recommend loading the Prusa Mini Assembly V15 into Fusion 360 and studying it carefully. This should answer most common questions.
For a clean routing of the display ribbon cable, a longer one than the original is required. I crimped it myself since it is not available in the correct length. The file "Kabelhalter.3mf" is designed to secure and hide this cable above the base plate.
Happy printing!
The extrusion endcap I modified is this one:
