Customizable Watch Band Keeper with Optional Tab

I created this as a replacement for my Garmin fitness watch's band keeper. I used a tutorial by user WilliamAAdams on creating rounded corners in OpenSCAD so that the band is more comfortable to wear.

The tab is rendered by default (but the customizer defaults the view so that it's on the backside). If you'd like to turn off the tab change Tab Rendered to 0.

Also, the value for the band's radius needs to be less than or equal to the band's width otherwise it won't work.
