Wago 221 Box With Switch

I remixed this design https://www.printables.com/model/844635-wago-221-junction-box-for-flex-wire-3-core-4-core/files

This is my first time trying to design or edit any 3d model so feedback is appreciated. 

I added a hole so I could add a mini rocker switch to use as a power switch for an air filter bento box.  I also added height to the box to make room for the switch terminals but you will need to bend them slightly so It will fit neatly.
