Spool holder and drybox for Enclosure V2.1 - with humidity sensor (downward facing position)

This version of the spool holder is with a downward facing rectagular hole for a humidity sensor.
Drybox is designed to be placed on the right side of the enclosure or on a high shelf so you can still read the values from the humidity sensor.
