Electrolux ChillFlex/Generic dual hose conversion

This **Electrolux connector plate** serves to make a **dual hose system for portable air conditioners**. Dual hose system allows connecting compressor inlet to the outside instead or wasting cool air from the inside, thus saving energy.

The Electrolux ChillFlex series can come in several sizes. Existing models on Thingiverse seems to match the _ChillFlex Pro_ air conditioners, but my _ChillFlex Gold_ is a bit larger, thus existing backplates are too small.

Rather that trying to make a backplate specific to my model, this is a **generic approach** consisting in designing a **simple connector plate that can be fit into any custom-made backplate**. I made my own using some rigid cardboard, cut in the shape of the original backplate.

The Electrolux connector comes from [Electrolux dual hose conversion for EXP35U538CW](https://www.thingiverse.com/thing:5421906) by Foppemoa (AC_RearPanel_ElectroluxConnection.obj), merged with a simple plate for attaching to the backplate.
