I really dislike most adjustable wrenches because they tend to slip out of place while I'm using them, forcing me to stop and readjust them. This is frustrating and interrupts my workflow. Despite this, I have to admit that they are still useful because of their adjustable nature. I just wish there was a better way to adjust them.

Knipex has designed a tool that combines the functionality of an adjustable wrench with the grip of a channel lock pliers. This tool, called the Knipex 8605150 6” Mini Pliers, may offer a better solution to the problem of adjustable wrenches slipping out of place.

The Finished Knipex Wrench Holder

The Files

To create a holder for the Knipex wrench using Fusion 360, I started by taking a photo of the wrench on top of a 1-inch grid. I made sure to hold the camera directly over the tool and to have good lighting from all sides. I also ensured that the camera was far enough away from the part to capture a clear image.

Next, I imported the image into Fusion 360 as a canvas and calibrated it using the grid in the background as reference points. I used a combination of the fit point spline and line tools to outline the profile of the tool. Once I was happy with the outline, I extruded a basic shape for the part. Because the tool is fairly simple, I only used two extrusion heights.

I added fillets to the edges of the component to soften them up. I also scaled the tool shape by creating an offset outline to allow it to slip in and out of the holder easily. I then created a relief around the handle of the tool to facilitate removal.

After creating a Gridfinity container that was approximately the size of the tool, I removed the magnetic holes on the bottom and used the body split tool to remove the side walls as well.

I then extruded the bottom of the container to match the height of the tool profile and centered the tool profile within the container. I used the combined tool to cut the tool profile out of the container, creating a holder that was tailored to the shape of the Knipex wrench.

To print this holder using ABS material and my standard settings, I would use the following parameters: 4 perimeters, 5 solid layers for the top and bottom, and a fill percentage of 40%. No supports would be needed for this print. The estimated amount of filament required for this print is 118 grams, and the print time would be just under 6 hours with my printer.
