I had a hole at the bottom of a garage wall. I didn't think spackling alone would work well, and I didn't have any leftover drywall to cut for a plug. So, I decided to see how well a 3D-printed drywall plug would work?

Overall, it worked well enough for a garage wall. For a better fit, I manually cut about one inch from the left side of my original/planned 3D-printed plug.
