YIHUA 939D+ Digital Soldering Station

This is a remix of the prior model, removing unnecessary filament from the back wall and base of the mount to reduce print time and filament use.  I've also added a desktop base for the soldering iron holder, sponge, flux and tip cleaner with similar hex/diamond cutouts for the same reason.  The black/green was just added as a matching accent to the desktop base as I ran out of black on the mount and the remainder printed in green.
