7/16 (11mm) hex knob handle 25mm or 60mm OD

thingiverse

This is a 25mm or 60mm outer diameter knob handle designed specifically for a hex bolt or nut with a diameter of 7/16 inches (11mm). In my experience, printing this design with PLA material results in undersized parts, but that's perfectly fine because it usually fits snugly on a 10mm hex bolt. If you want to use the original 7/16 inch (11 mm) nut or bolt, simply press it into place - I'll be sharing a tutorial video on my YouTube channel soon, titled "Camera Boom," where I'll demonstrate this process in more detail. Alternatively, if your printer allows for scaling, try increasing the size of your print by about 102.4% (in Cura, 100% is the standard size) to achieve the intended dimensions. Fortunately, a support structure isn't required when printing the 25mm handle.
