The author remixed this model.
I've recreated this in Fusion360 rather than OpenSCAD because it's more intuitive for me. I've adjusted the lengths and the curvature to be a little more effective in my experience.
I've also added a void in the main stick so that you could loop some string, a twist tie, or something else through in order to hang this from something, which is how we store it nearthe vacuum.
I also thickened the part to make it a little more durable, and smoothed out the curve and the edges, just for aesthetics.
