This model adds downward feed as well as moves the hygrometer to be facing the same side as the PTFE tubing.  Included are files for a large desiccant bin.  If you decide to use the straight through PTFE connection you can print the “PTFE Connector Drill Guide for side", and the PTFE nut to attach the 10mm connector.  I personally don't use this as it makes removing the top more difficult.  There is a file to help you cut the inner tube to put over the front wheels.  as well as a template to aid in cutting the base for the 10mm connector.
