Hand-Screw Clamp - Long Threads

When I showed my prints of the original design to my brother he asked me if I can print few for him. He is scale models builder and he need such clamps. But for his projects a little bit longer threads will be a nice to have.
I did remix of Threadsx2.stl element to have them longer: 2x and 3x.
Printing in ABS (like me) could be a little challenge without wrapping so you can use the version with holding pads.

Preview shows some nasty connecting points but the 3D view is OK. And of course the stl could be sliced and printed without problems as you can see on pictures.
