This OpenSCAD library generates a K8200/3Drag frame mounting clamp with locking.  This fast-clamp as been designed to be used to make stong mounts for whatever: extruders, drill, laser, fan, cam... and more. The change is easy and fast because it do not require any tool. As bonus it is possible to add holes for standard fixing, using M5 screws and squared nuts.2 main modules are defined:   clip(height, holes, h_pos), to be used in custom mount design for your device.   click(height), 2 parts to fix the clip: see pics to know how to assemble the fast-clamp. This design is experimental and may change, but usable as is. Thanks to makers:  http://www.thingiverse.com/thing:424674 for a simple clamp         http://www.thingiverse.com/thing:444323 for the alu profile.  The STL file is for a test clamp, height 10 mm.ver. 0.5.1  23/07/2015 added lower and upper limits to adjust_link ver. 0.5    16/07/2015 base version
