I'm not sure why but billiamthesecond's version clamp area wasn't large enough to snap on to my build plate. It looks like the same build plate he's using but it needed opened about 3.5mm or so to work. In case anyone else had this issue I uploaded this. I also added a slight slant to the top in order to cut out a little material and make it look a tiny bit different so I knew which version it was when opening it.

same settings.
