Oxo dish scrub brush holder

thingiverse

I am absolutely crazy about the Oxo dishwashing brush, specifically not the most recent model which spouts the detergent, but rather its predecessor that dribbles it - what a much more sensible quantity! The newer version is acceptable, yet you have to dilute the detergent and replenish it frequently, which can be really annoying. However, this old brush starts dripping enough detergent to create quite a mess on my kitchen counter, so I ended up being tired of it. This stand has a drip-catching pan underneath the brush head and positions the handle at an angle that greatly minimizes the possibility of detergent seeping out the rubber activating/filling button or into the brush. How I Designed This Stand I managed to come up with the brush end shape by taping its bristles aside, then taking a photo straight-on using a lengthy focal length. After that, I cropped the photo and attached it to a sketch plane in Autodesk Fusion, scaled it to real size based on the provided ruler in the photo, and eventually selected an arc that looked like a good fit. Next, I inserted this arc into a smaller test piece which I printed initially to verify that its shape was accurate - just one attempt proved sufficient. For the handle, I utilized a profile measuring tool (which essentially comprises numerous stiff wires kept next to each other in a slidable clip/handle). I then drew its outline on paper and scanned it, attaching it to another sketch in Fusion and merging it with half of an ellipse. Although I could have used this approach for the brush head too, I hadn't considered it yet. I fine-tuned the horizontal brush angle so that the detergent level remained relatively equidistant from the fill/actuator plug and the hole towards the bristles - all in an attempt to reduce leakage. Placing the brush downwards should largely prevent leaks around the fill button unless you refill it really thoroughly. Additionally, the drip pan will easily manage any falling matter from the bristles. I printed this stand in ABS across two separate sections, after which I sanded and scraped specific parts for a nicer appearance. Following that, I used acetone vapor at room temperature to make them shiny and water-repellent for 45 minutes - let it dry for an hour, then bonded them together with acetone.
