Right after I got my printer, I found myself looking for something like this. I could only find a finished product on Etsy, so I ended up making and printing a worse version.

However ugly it may be, it works :)

I would love for someone who actually knows how to make 3D models to remix this and make it good.

The XL is at a 27 degree angle and the OG deck is at a 55 degree angle.

EDIT : This is the new version with less needed material and better cable managment

The fit for the XL is a press fit (might have to adjust print settings here).

Print with supports, I used tree and slim tree in Orca slicer, some parts of the print are a not great, but still works. I would for a overall good print, recommend organic tree support.
