The guard that goes around the USB-C connector on my Dell WD15 Docking Station broke. This is a perfect fit to replace it. The print profile uploaded uses a 0.12mm layer height which is what I found to be the best. I chose to print the models individually as well so that if one messes up, you can just remove the one that didn't fail and reprint the failed one. The two pieces should snap together with a snug fit. I also chose to use a dab of glue to hold the two together but I just wanted to make sure it never came off. Please feel free to reach out with any suggestions or issues that you have seen with the model or print profile. Happy printing!
