I needed to keep my Philips Hue® outdoor LED strip unplugged in the garden, and I decided to print a little cap to screw on the connector to avoid ruining it with humidity and weather. The M15x1 thread seems hard to print, but with the correct settings I had no trouble bringing it done.
The model in the photo was printed with a .6 mm nozzle, 2 perimeters, Arachne-generated perimeters, adaptive layers, and .15 mm base layer height. The result was optimal, and got screwed on the connector pretty easily. Since it got finished with this nozzle, a .4 nozzle or smaller could only improve quality.
The author marked this model as their own original creation.
