This is an example printed electronic, using the solder-free 3D-PCB libraryhttp://www.thingiverse.com/thing:21975

It is an LED flashlight, made entirely out of printed parts and 4 lengths of conductive thread, plus 2 batteries and 4 LEDs.

Detailed instructions for buildling this, as well as for using 3D-PCB in general:http://www.instructables.com/id/3D-Printed-Circuit-Boards-for-solder-free-printab/ , as part of the Make-It-Real Challenge (so your vote would be greatly appreciated!).

Note: If you are thinking to build, I suggest first test-printing the electronics_top, along with a switch_toggle and a peg_cap. I haven't tested it on many printers, and these pieces have the finest tuned tolerances

Instructions

Tools and Materials
Currently, it has only been thoroughly tested on the MakerBot Replicator, with ABS plastic. Support for Up! soon (but the different tolerances prevent immediate support).

I have tried several types of conductive thread, and the best so far (by a wide margin) is:http://members.shaw.ca/ubik/thread/order.html

Instructions
Print using the standard replicator defaults or equivalent, with no raft or support:
1x electronics top
1x electronics bottom
1x tube
1x cap
1x slide_switch
11x peg caps

Also acquire:
4x 5mm LEDs, you probably want white
2x AAA batteries
4x conductive thread -- 2x~12in, 2x~18in

The uploaded drawing shows how to wire up the circuit; Detailed wrapping instructions can be found on http://www.instructables.com/id/3D-Printed-Circuit-Boards-for-solder-free-printab/step4/Useful-Example-3D-Printed-LED-Flashlight/
