Sink hole cap holder

thingiverse

I needed to replace the original cap holder because it wasn't allowing water to drain fast enough. Its design was unusual, relying on a bolt to secure the cap to the holder, and one side featured a cap with a diameter very close to the sink hole, preventing adequate drainage. I suspect this was an attempt to prevent items from accidentally being washed down the drain. I don't need this feature because my sink cap is already positioned closely enough to the sink hole, eliminating any risk of this occurring. To design the new holder, I measured the original using a digital caliper and transferred these measurements to SketchUp. I then redesigned the holder, removing the cap so that water can flow freely between the fins, and extended its length to eliminate the need for a bolt to secure it. The cap now sits atop the holder. My initial attempt failed because this was my first time designing and printing something from scratch. Unbeknownst to me, the measurements in SketchUp do not directly translate to actual printed results. In my case, the inner hole was approximately 10% smaller than expected, while the fins were thicker. I also attempted to change filaments mid-print, knowing it would be a risk, but ultimately resulting in a 2mm X offset when printing resumed. Fortunately, this failure occurred around 30% into the print, allowing me to identify and correct flaws in my design. The revised version printed successfully and matched the sink hole and cap perfectly. I'm pleased with the outcome, and time will tell if this design is truly effective. I used Cura 4.0 BETA for printing and have included my printer settings below. Feel free to modify the design using the attached SketchUp file to suit your needs.
