News: The successor is in town. You may take a look at my latest shiny gadget , the pcb exposure frame. Use this as pictureframe or the techie's nameplate as well. http://www.thingiverse.com/thing:503299 Derivate of my versatile holder V4 holds pcb 60mm x 100mm x 1.75mm (slide in) reduced hight, rails are better aligned , more or less perfectly symmetrical improved barclamp , requires 3mm screws improved finish . Look here: http://www.thingiverse.com/thing:501886 and here: http://www.thingiverse.com/thing:502919 .

Good printer accuracy required. Be aware. The top notch holding the pcb is tiny. . The files:
