Nothing really special about how to print this.

I don't think tolerances particularly matter.

I have attached .stl, stp, and fusion files so that you can more easily adjust to fit your laptop.

Trying to get the charger to allign was a bit of a struggle for me. I'd strongly recommend just taking a photo of your laptop's ports, uploading it to fusion, scaling it correctly, and then sketching around that. It's so much easier and wish I'd just thought of doing it that way originally.

Hopefully the existing cutout will just work for you.

The existing laptop channel width is 25.8mm and length 249mm.

It's height is to allow you to plug in HDMI cables and USB's from the bottom.
