I'm about to make several hundreds of idc cables with idc plug on both sides. So I needed the tool for this.
Print it with 45 degrees (to better fit the table), 2 perimeters, 90% fill, 0.33mm layer height, 50-60 mm/sec max, to be more durable.
When printed, put (push hard) the handles into rectangle element.
There is some improvements - the clamper is little springy, so it goes opened rather than remains squeezed after clamping.
There are three tooths on curved-planes that are rolling on each other to be more stable in operation.
