Oldie Wrench

myminifactory

Everyones favorite Canadian AvE recently posted a video about a wrench designed by Hand Tool Rescue. The design caught my eye, and I thought it would work well as a 3D printed design for a wrench clamp combo. My design may not be as robust as the metal one made by Hand Tool Rescue, but it's surprisingly strong, especially considering I didn't optimize the print settings. I created this model entirely in Fusion 360 using a screencap of AvE's video to get the general outline. It fits nicely in the hand, and everything else is my own design. The main difference between mine and the original is that mine doesn't have a sliding mechanism to show off the shaft, which I omitted for simplicity and added strength. Some Assembly Required This model comes with four different STL files. The hardest part about printing it is getting the thread.stl and nut.stl to print correctly, as they require a smaller layer height (I recommend keeping them consistent to ensure proper threading). A high infill density is also recommended for these parts. The other two files can be printed with a 30% infill, but mileage may vary depending on filament and intended use. Assembly of the parts requires some super glue or similar adhesive. The thread.stl has a hex on one end that should fit snugly into a hex on the head.stl. Before gluing, I recommend inserting the thread into a drill and holding the nut with pliers to slowly work it through. This may require going back and forth a few times if there are any rough parts. If issues arise with supports, consider sanding the head before assembling it into the handle. The handle should slide in easily without resistance. If it's hard to push in, it will be even harder to pull out!
