The lever for the air diverter slider on most of my floor registers broke, so I designed this replacement. It fits many of the standard 10" x 4" models, and should allow for reuse of the original diverters and slider. I also designed a replacement diverter (uploaded separately), as the originals often broke as well. The model requires print supports (works best with PLC Support for clean removal).

I can't guarantee exactly which makes/models this fits - only that it worked for several of the different registers in my home.
