Kan Not Twist Clamp V2 100% Printed Parts

If you have ever worked as a fabricator or a machinist you will be familiar with this clamp. With this clamp the load is distributed over two parallel jaws versus one jaw as with a c-clamp. This helps keeps your workpiece from walking. Additionally the handle positioned perpendicular to the clamp load which keeps the clamp from twisting hence its name. I also like that you can remove the clamp one handed as well.

The design of this clamp has been optimized for 3D Printing. It only uses 3D printed parts with no glue or fasteners. This is the second iteration of the design. For this version increased the thread size to make it stronger and changed the way that the frame splits so its stronger during assembly. Supports are not required if printed in the provided orientation.

I printed the arms out of Jabil’s PA 4535CF, for stiffness. The nut is printed out of [Jabil’s PA 0600, for strength.

Assembly note: The arms don't come apart very easily, I would not recommend putting them together unless you have all the parts in place. If you do have to take them apart make sure pull them apart evenly, if they get cocked while you are pulling them apart the pins could break. After the parts are together, use the pins to lock them in place.

Note: Assembly model for reference only.
