This is the famous EMH Mobile Emitter as seen in Star Trek Voyager. In Star Trek Voyager the EMH (Emergency Medical Hologram) acquires this from the 29th century in the episode "Future's End Part 2". You may wish to scale it up because it is a little small. Print on standard resolution in either a metallic silver/grey plastic or print normally and then paint with a few liberal coats of paint. This should take from away the fact that you can see the lines were printed. I used a Ford Car paint - Polaris grey which is a metallic paint and has small particulates in which create that light refracting effect seen on screen. In the Pictures you will see one screen shot from the show, one on a green mat from here: http://www.therpf.com/f9/st-voyager-mobile-emitter-86985/ Which shows a build of a Non-3D-Printed version, and photos of mine with assorted Isolinear chips and PADD's. I am willing to post the files for the Isolinear chips at some point: -TNG style -Voyager style -Square -Rectangular The square and rectangular ones have 'USS Enterprise-E' on them but the others will have to have a printed label added. The PADD's measurements were (Metric I'm afraid) taken from here: http://www.therpf.com/f9/star-trek-props-tricorders-padd-78922/ If not search PADD dimensions on Google. The same Ford Car paint was used for the grey PADD and Ford Tango Red was used for the Engineering PADD. After painting the emitter, any old circuit board will do as long as you can cut it down and glue it in place matching up some patterns, this is my next step. In the mean time I am using a small piece of green paper with a pattern on. The images show the circuit board I intend to use. I also have some TOS engineering tools in .dxf format to upload if requested. Please upload any makes! I would love to see what you do with them!
