I wanted a cleaner way to mount my PS4 to my IKEA Jerker desk, so I designed a bracket for that purpose! It's designed to keep the console snug against the desk without being obtrusive. It's over-engineered to be significantly more sturdy than it really needs to be, so don't be afraid to use it for things like wall mounting as well!
I've also uploaded the 123D Design file if anyone wants to remix / improve it!
September 2017 update:
First, thanks everyone who has liked / collected this. It means a lot. I wanted to let you know that this design ALSO works well for a PS4 Pro! It's a little more snug than a standard PS4 because Sony put a bunch of "feet" on the bottom of the Pro, so the one foot in the middle makes this a snug fit on my IKEA Jerker. However it does fit and being a little more snug is probably not a bad thing!
Printed on a Makergear M2 w/ v3b hot end, Black PLA. I went with a 25% infill, but given the reinforcing braces and the general thickness of the piece, you can probably get away with 20% infill and save some plastic and print time. Also you can see from the one photo that you'll want to generate support material for it.
This took almost 9 hours on my M2, so don't start it during a storm!
