I printed the original model to attach to my table at work. I decide to attempt to make one to attach to our shelving unit that holds all of our rag boxes at work. This is what I came up with. I beefed it up a bit as my coworkers are pretty hard on shop tools. I guessed on the leg diameter to be 1" but made the model 25mm. It fits on the 1" with a little bit of a gap. I just attached it with some heavy duty zip ties. I added the flats on the side so it can be printed that way using supports. That's the best way I could think of. Still pretty new to making models and 3D printing. Forgot to take pictures, i'll add some later.
The author remixed this model.
I changed it from a flat mount that can be screwed to a wall to a mount that can be attached to a pipe.
