This is the final part of the LaserDock magnetic docking station, called Part C. It spawns a cover for the LaserDock device. Once all three parts of this magnetic docking station are assembled you can use it for convenient mounting and dismounting of an engraving and cutting laser head on your CNC machine. The device was originally designed to work with any 6 W engraving and cutting laser head from Opt Lasers. You could also download the file from the original webpage:
