I tried to break the red clamp by cranking it down to the kitchen counter as hard as I could and then pulling on the drawers it was blocking (see photos). It flexed a lot when being clamped and showed some stress on an inside corner but it seemed very strong and it didn't feel like it was going to give way. The clamp returned to it's normal shape and did not warp from being under that much pressure. I will try printing clamps with less thickness and run the same test to see how much difference it really makes. The original inspiration for making these stronger clamps was the popular "G-Clamp fully printable" that was quite easy to make fail when cranked down - deformation and bolt breakage. For extra strength in practical use, print the screw part with 100% infill since there are some weak points, like where the ball connects. Adding STL files to make that easy to do. # Updates ## Initial Release 3.1 - Exposed more customization options to fiddle with, but something is still buggy when thickness is over 18mm ## September 13 2018 3.2 - Corrected the thickness bug, it now keeps a complete threaded hole (tested working from 5mm to 50mm) and reduced the default knurling fineness (complexity) to 500 so it's got a fighting chance of rendering the web browser preview. Lower this number to what you want it to be just before creating the STL. If your browser won't render the preview of all the parts at once, you can turn off the visibility of all but one of the parts at a time to adjust them until the final create rendering action where they should all be visible but not assem
