This hangs a dish cloth off the end of a counter (specifically, currently, my counter.) Printed in Bambu Basic PLA.
This was one of the first few things I designed, so it was still built in SketchUp, and is unfortunately not parametric. I have included the original SketchUp, STL, and Bambu 3MF files, including previous design revisions – everything is provided as-is, feel free to modify or do whatever you like to the design!
This mounts to the counter with 3M sticky pads. One advantage of this technique is the foam adds shock absorption, grealty increasing how resilient this bar is to being bumped and leaned against. After 5 months of (ab)use, I can say mine has yet to develop a failure of any kind. Your mileage may vary, of course. Enjoy!
