here I did my best to design a hopefully accurate "C1 personal comlink" like used by Luke Skywalker in Star Wars - A new Hope. I own a screenaccurate Stormtrooper armor. So with the helmes mictips and a belt, I was able to measure the comlinks size photogrammetricly.
(One note here: The mictip was designed without the letters and numbers onto it. - Maybe you find better ones on thingiverse.)
There are two versions of the botton cap (V1 and V2) available, because it was really hard to see on the pictures what shape it actually has. So you can pick your favorite cap.
Actually I already designed this comlink back in the year 2013 and I totally forgot about it. So there it is for you all now. Have fun!
Just simple print all parts with full infill and 0.1 or 0.2mm layerheight. You need to print the mid section two times and glue together. Only the mictip should be printed with support material. I put a small piece of netting wire into the mictip. To smooth the parts, I brushed it a bit with acetone.
