Update 8/26/23:
I remodeled in FreeCAD (as best I could, being new to CAD). It should be fully parametric with all values being found on the spreadsheet. Added FCStd and STEP file.
Update 12/15/22:
I made a version that has a thicker ring to it so they don't flex as easy. Denoted by “_thicker” in the STL name.
I made this to hold our reusable dish scrubber wand thing. Our sink does not have a divider and is mounted under the granite. This wraps around the faucet stem and hangs over the edge of the sink. I tossed this together in tinkercad and it can be found here: https://www.tinkercad.com/things/e9je04dI7fH
There are two versions. V2 has a block behind where the wand goes to support it against the sink. Either work fine in my testing. The edge of my faucet is roughly 41mm from the edge of the sink.
The author marked this model as their own original creation.
