Tinker friendly Lack enclosure for Anet A8

This is a modified version of the Tinker-Friendly Lack Enclosure by zuspiel (http://www.thingiverse.com/thing:2012384), in order to be able to fit the printer Anet A8. The lower part is the one modified, being extended to 40mm (the whole set lifts the Lack table 70mm). I also included the top part, so you can download the whole set at once.
