The base of the Ikea Pendant lights (https://www.ikea.com/ca/en/p/ikea-ps-2014-pendant-lamp-white-copper-color-30311492) does not leave much space for hiding mistakes when cutting drywall sheets. Instead of recutting the gypsum panel I opted to 3D print a small brim for the base of the light instead. It both hides the minor miss-cut and looks like it could have been designed with the brim from the start.
I will be installing the light either tonight or tomorrow, so I will post a final picture of the installed model then.
The author marked this model as their own original creation.
