Have fun!
P.S: I had 2 PSU's, one that came with my Ender 3 Pro 4 years ago, and the one I just bought, the lower screw hole for these two PSUs were different, and there was a 2 mm offset between the old and new models, otherwise they are exactly the same. My 3D model matches the new PSU model, probably comes with the Ender 3 Pro models for years now… But, better check before printing, worst case, don't bolt the bottom screws as the plastic base holds that part in place already…
