Widened Filler Module

Simple remix to allow most 2 or 3 prong US style plugs through on the back of the filler module. I measured poorly on the first attempt and the resulting print was too small to pass the cord through. I remeasured and widened the hole to 34mm. Most plugs should now fit, however I did not reprint, and opted to run my cord a different way, so as of now this is untested.
