Cutaway LED Flashlight (solder-free)
by CarryTheWhat, published
This is an example printed electronic, using the solder-free 3D-PCB library http://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.
<b>Detailed instructions</b> 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!).
<b>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</b>

<b>Tools and Materials</b> 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
<b>Instructions</b> 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; <b>Detailed wrapping instructions</b> can be found on http://www.instructables.com/id/3D-Printed-Circuit-Boards-for-solder-free-printab/step4/Useful-Example-3D-Printed-LED-Flashlight/
