3D Printed Kant Twist Clamp

Kant Twist Clamp Optimized for 3D Printing, 100% Printed Parts I'm a big fan of this clamp! If you've ever worked as a fabricator or machinist, you'll be familiar with this clamp. It's also useful for woodworking, although I'm sure it has its own purpose there too. With a Kant Twist, the load is distributed over two parallel jaws versus one jaw like a c-clamp. This helps keep your workpiece from walking. Additionally, the handle positioned perpendicular to the clamp load keeps the clamp from twisting, hence the name "Kant Twist". I also like this because you can remove the clamp with one hand as well. You can find designs for the Kant Twist all over the internet, but they're designed to be made out of steel. If you try to print the original design out of plastic, it won't work very well. My goal was to create a 3D printed Kant Twist that actually works, only uses 3D printed parts (no glue or fasteners), and doesn't require any supports. The thread on the original version was too small and not strong enough when printed, so I changed it from a 5/16" UNF to a 1/2" trapezoidal thread. I integrated the spacers into the legs and made them larger to reduce the number of parts and increase strength. I also changed their design so they snap together, held in place by a locking pin. They're riveted on with the steel version, but I could have used glue instead – that would be cheating! I also made the legs thicker to increase strength and made some other changes to make it printable without supports. Printing note: Print everything except the tread with 3 perimeters and 25% infill. Print the thread with 6 perimeters and 50% infill. You can always increase the infill if you want it stronger. Assembly note: The arms don't come apart easily, so I wouldn't recommend putting them together unless you have all the parts in place. If you do have to take them apart, make sure to pull them apart evenly – if they get cocked while you're pulling them apart, the pins could break.
