Ender 3 Pro Power Supply Holder

This is a holder for the MeanWell LRS 350 power supply that mounts to a 4040 extrusion.

After printing the power supply holder from kevinakasam's Belt Driven Ender 3 mod, I noticed the gap at the top between the PSU.

The Ender 3 Pro has a different PSU than the stock Ender 3, that is not only thinner, but the mount holes are different, too. So I remixed kevinakasam's version to fit my Ender 3 Pro.

I also made the hole for the cables a little bit bigger.

Update 2025-02-07:

I added a file with a top opening that is a bit wider (by 0.35mm). The original one has a clearance of 0.5mm, while the new one has 0.85mm. In case your PSU is thicker than the specified 30mm or 0.5mm is a bit tight for your printer use the file with larger tolerances. Or use the step file to adjust to your needs. Thanks @Bild_696969_2831092 for bringing this up.

Notes:

The bridge at the top is quite long, but as the surface is on the inside and never visible, you may get away without supports.

However, you probably want to do a quick bridge test before and tune your settings if necessary.

License:

I designed this with a non-commercial license of Fusion360, so I can't allow commercial use of the files included. However, if you don't use those files in your remix, it's fine with me if you do whatever you want with your version (read: I'd license the idea of my design/modifications under CC-BY, but I can't do this for the files).
