WHAT?! Phillips head screws?!! Why not Pentalobe or at least Torx?!!!
Heresy!!!!The only thing that would have made this a better hack would have been the use of a real hack saw!!
This does show the biggest failing of 3-D printers, at least the early models; not great for flat surfaces.
Similar to the 128K Mac using 96 dpi, a closer look will reveal the 'pixel' spacing. I hear that newer 3-D printers and/or different 'inks' do a much better job. But, also similar to Macs, they are more expensive.
